Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542286, here are decompositions:

  • 5 + 31542281 = 31542286
  • 53 + 31542233 = 31542286
  • 89 + 31542197 = 31542286
  • 137 + 31542149 = 31542286
  • 173 + 31542113 = 31542286
  • 263 + 31542023 = 31542286
  • 353 + 31541933 = 31542286
  • 383 + 31541903 = 31542286

Showing the first eight; more decompositions exist.
