Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559098, here are decompositions:

5 + 31559093 = 31559098
17 + 31559081 = 31559098
29 + 31559069 = 31559098
47 + 31559051 = 31559098
71 + 31559027 = 31559098
101 + 31558997 = 31559098
239 + 31558859 = 31559098
251 + 31558847 = 31559098

Showing the first eight; more decompositions exist.
