Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532590, here are decompositions:

3 + 31532587 = 31532590
17 + 31532573 = 31532590
83 + 31532507 = 31532590
101 + 31532489 = 31532590
113 + 31532477 = 31532590
251 + 31532339 = 31532590
311 + 31532279 = 31532590
449 + 31532141 = 31532590

Showing the first eight; more decompositions exist.
