Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496598, here are decompositions:

5 + 31496593 = 31496598
11 + 31496587 = 31496598
31 + 31496567 = 31496598
47 + 31496551 = 31496598
59 + 31496539 = 31496598
61 + 31496537 = 31496598
79 + 31496519 = 31496598
109 + 31496489 = 31496598

Showing the first eight; more decompositions exist.
