Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529598, here are decompositions:

5 + 31529593 = 31529598
31 + 31529567 = 31529598
41 + 31529557 = 31529598
47 + 31529551 = 31529598
59 + 31529539 = 31529598
127 + 31529471 = 31529598
151 + 31529447 = 31529598
167 + 31529431 = 31529598

Showing the first eight; more decompositions exist.
