Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590464, here are decompositions:

13 + 31590451 = 31590464
43 + 31590421 = 31590464
67 + 31590397 = 31590464
151 + 31590313 = 31590464
223 + 31590241 = 31590464
277 + 31590187 = 31590464
331 + 31590133 = 31590464
457 + 31590007 = 31590464

Showing the first eight; more decompositions exist.
