Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500688, here are decompositions:

  • 61 + 2147500627 = 2147500688
  • 97 + 2147500591 = 2147500688
  • 127 + 2147500561 = 2147500688
  • 181 + 2147500507 = 2147500688
  • 337 + 2147500351 = 2147500688
  • 349 + 2147500339 = 2147500688
  • 577 + 2147500111 = 2147500688
  • 607 + 2147500081 = 2147500688

Showing the first eight; more decompositions exist.
