Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448414, here are decompositions:

37 + 31448377 = 31448414
181 + 31448233 = 31448414
223 + 31448191 = 31448414
397 + 31448017 = 31448414
457 + 31447957 = 31448414
463 + 31447951 = 31448414
577 + 31447837 = 31448414
601 + 31447813 = 31448414

Showing the first eight; more decompositions exist.
