Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449314, here are decompositions:

67 + 31449247 = 31449314
73 + 31449241 = 31449314
151 + 31449163 = 31449314
271 + 31449043 = 31449314
277 + 31449037 = 31449314
601 + 31448713 = 31449314
607 + 31448707 = 31449314
727 + 31448587 = 31449314

Showing the first eight; more decompositions exist.
