Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472846, here are decompositions:

  • 59 + 2147472787 = 2147472846
  • 89 + 2147472757 = 2147472846
  • 149 + 2147472697 = 2147472846
  • 157 + 2147472689 = 2147472846
  • 163 + 2147472683 = 2147472846
  • 229 + 2147472617 = 2147472846
  • 347 + 2147472499 = 2147472846
  • 397 + 2147472449 = 2147472846

Showing the first eight; more decompositions exist.
