Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448248, here are decompositions:

  • 47 + 31448201 = 31448248
  • 107 + 31448141 = 31448248
  • 137 + 31448111 = 31448248
  • 179 + 31448069 = 31448248
  • 191 + 31448057 = 31448248
  • 281 + 31447967 = 31448248
  • 317 + 31447931 = 31448248
  • 347 + 31447901 = 31448248

Showing the first eight; more decompositions exist.
