Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558708, here are decompositions:

59 + 31558649 = 31558708
89 + 31558619 = 31558708
101 + 31558607 = 31558708
179 + 31558529 = 31558708
239 + 31558469 = 31558708
317 + 31558391 = 31558708
479 + 31558229 = 31558708
509 + 31558199 = 31558708

Showing the first eight; more decompositions exist.
