Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448176, here are decompositions:

5 + 31448171 = 31448176
107 + 31448069 = 31448176
503 + 31447673 = 31448176
509 + 31447667 = 31448176
569 + 31447607 = 31448176
593 + 31447583 = 31448176
647 + 31447529 = 31448176
719 + 31447457 = 31448176

Showing the first eight; more decompositions exist.
