Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448276, here are decompositions:

43 + 31448233 = 31448276
127 + 31448149 = 31448276
313 + 31447963 = 31448276
373 + 31447903 = 31448276
439 + 31447837 = 31448276
463 + 31447813 = 31448276
619 + 31447657 = 31448276
883 + 31447393 = 31448276

Showing the first eight; more decompositions exist.
