Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550598, here are decompositions:

5 + 31550593 = 31550598
11 + 31550587 = 31550598
17 + 31550581 = 31550598
29 + 31550569 = 31550598
41 + 31550557 = 31550598
59 + 31550539 = 31550598
61 + 31550537 = 31550598
67 + 31550531 = 31550598

Showing the first eight; more decompositions exist.
