Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508598, here are decompositions:

19 + 31508579 = 31508598
29 + 31508569 = 31508598
31 + 31508567 = 31508598
41 + 31508557 = 31508598
71 + 31508527 = 31508598
89 + 31508509 = 31508598
137 + 31508461 = 31508598
181 + 31508417 = 31508598

Showing the first eight; more decompositions exist.
