Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490794, here are decompositions:

53 + 31490741 = 31490794
107 + 31490687 = 31490794
173 + 31490621 = 31490794
227 + 31490567 = 31490794
347 + 31490447 = 31490794
431 + 31490363 = 31490794
443 + 31490351 = 31490794
557 + 31490237 = 31490794

Showing the first eight; more decompositions exist.
