Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625286, here are decompositions:

5 + 31625281 = 31625286
23 + 31625263 = 31625286
107 + 31625179 = 31625286
137 + 31625149 = 31625286
139 + 31625147 = 31625286
227 + 31625059 = 31625286
229 + 31625057 = 31625286
307 + 31624979 = 31625286

Showing the first eight; more decompositions exist.
