Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490598, here are decompositions:

5 + 31490593 = 31490598
11 + 31490587 = 31490598
31 + 31490567 = 31490598
71 + 31490527 = 31490598
89 + 31490509 = 31490598
101 + 31490497 = 31490598
109 + 31490489 = 31490598
137 + 31490461 = 31490598

Showing the first eight; more decompositions exist.
