Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450798, here are decompositions:

11 + 31450787 = 31450798
17 + 31450781 = 31450798
59 + 31450739 = 31450798
131 + 31450667 = 31450798
179 + 31450619 = 31450798
257 + 31450541 = 31450798
311 + 31450487 = 31450798
347 + 31450451 = 31450798

Showing the first eight; more decompositions exist.
