Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147551162, here are decompositions:

  • 23 + 2147551139 = 2147551162
  • 293 + 2147550869 = 2147551162
  • 311 + 2147550851 = 2147551162
  • 431 + 2147550731 = 2147551162
  • 563 + 2147550599 = 2147551162
  • 569 + 2147550593 = 2147551162
  • 761 + 2147550401 = 2147551162
  • 821 + 2147550341 = 2147551162

Showing the first eight; more decompositions exist.
