Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526146, here are decompositions:

  • 5 + 31526141 = 31526146
  • 59 + 31526087 = 31526146
  • 83 + 31526063 = 31526146
  • 89 + 31526057 = 31526146
  • 227 + 31525919 = 31526146
  • 233 + 31525913 = 31526146
  • 257 + 31525889 = 31526146
  • 347 + 31525799 = 31526146

Showing the first eight; more decompositions exist.
