Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496590, here are decompositions:

3 + 31496587 = 31496590
17 + 31496573 = 31496590
23 + 31496567 = 31496590
53 + 31496537 = 31496590
71 + 31496519 = 31496590
101 + 31496489 = 31496590
149 + 31496441 = 31496590
173 + 31496417 = 31496590

Showing the first eight; more decompositions exist.
