Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497754, here are decompositions:

  • 3 + 31497751 = 31497754
  • 17 + 31497737 = 31497754
  • 47 + 31497707 = 31497754
  • 53 + 31497701 = 31497754
  • 83 + 31497671 = 31497754
  • 227 + 31497527 = 31497754
  • 263 + 31497491 = 31497754
  • 293 + 31497461 = 31497754

Showing the first eight; more decompositions exist.
