Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451044, here are decompositions:

11 + 31451033 = 31451044
47 + 31450997 = 31451044
83 + 31450961 = 31451044
197 + 31450847 = 31451044
257 + 31450787 = 31451044
263 + 31450781 = 31451044
281 + 31450763 = 31451044
431 + 31450613 = 31451044

Showing the first eight; more decompositions exist.
