Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448402, here are decompositions:

  • 79 + 31448323 = 31448402
  • 103 + 31448299 = 31448402
  • 109 + 31448293 = 31448402
  • 211 + 31448191 = 31448402
  • 241 + 31448161 = 31448402
  • 331 + 31448071 = 31448402
  • 379 + 31448023 = 31448402
  • 439 + 31447963 = 31448402

Showing the first eight; more decompositions exist.
