Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449134, here are decompositions:

7 + 31449127 = 31449134
97 + 31449037 = 31449134
271 + 31448863 = 31449134
313 + 31448821 = 31449134
331 + 31448803 = 31449134
421 + 31448713 = 31449134
487 + 31448647 = 31449134
547 + 31448587 = 31449134

Showing the first eight; more decompositions exist.
