Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525482, here are decompositions:

5 + 31525477 = 31525482
61 + 31525421 = 31525482
103 + 31525379 = 31525482
139 + 31525343 = 31525482
151 + 31525331 = 31525482
193 + 31525289 = 31525482
199 + 31525283 = 31525482
239 + 31525243 = 31525482

Showing the first eight; more decompositions exist.
