Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448204, here are decompositions:

  • 3 + 31448201 = 31448204
  • 13 + 31448191 = 31448204
  • 43 + 31448161 = 31448204
  • 181 + 31448023 = 31448204
  • 241 + 31447963 = 31448204
  • 367 + 31447837 = 31448204
  • 421 + 31447783 = 31448204
  • 523 + 31447681 = 31448204

Showing the first eight; more decompositions exist.
