Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542764, here are decompositions:

  • 37 + 31542727 = 31542764
  • 61 + 31542703 = 31542764
  • 67 + 31542697 = 31542764
  • 151 + 31542613 = 31542764
  • 241 + 31542523 = 31542764
  • 277 + 31542487 = 31542764
  • 307 + 31542457 = 31542764
  • 367 + 31542397 = 31542764

Showing the first eight; more decompositions exist.
