Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448996, here are decompositions:

97 + 31448899 = 31448996
157 + 31448839 = 31448996
193 + 31448803 = 31448996
277 + 31448719 = 31448996
283 + 31448713 = 31448996
349 + 31448647 = 31448996
409 + 31448587 = 31448996
463 + 31448533 = 31448996

Showing the first eight; more decompositions exist.
