Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449548, here are decompositions:

127 + 31449421 = 31449548
139 + 31449409 = 31449548
307 + 31449241 = 31449548
421 + 31449127 = 31449548
709 + 31448839 = 31449548
727 + 31448821 = 31449548
829 + 31448719 = 31449548
967 + 31448581 = 31449548

Showing the first eight; more decompositions exist.
