Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493590, here are decompositions:

17 + 31493573 = 31493590
71 + 31493519 = 31493590
113 + 31493477 = 31493590
251 + 31493339 = 31493590
269 + 31493321 = 31493590
389 + 31493201 = 31493590
419 + 31493171 = 31493590
521 + 31493069 = 31493590

Showing the first eight; more decompositions exist.
