Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559654, here are decompositions:

3 + 31559651 = 31559654
13 + 31559641 = 31559654
31 + 31559623 = 31559654
211 + 31559443 = 31559654
241 + 31559413 = 31559654
271 + 31559383 = 31559654
283 + 31559371 = 31559654
337 + 31559317 = 31559654

Showing the first eight; more decompositions exist.
