Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556410, here are decompositions:

3 + 31556407 = 31556410
29 + 31556381 = 31556410
101 + 31556309 = 31556410
107 + 31556303 = 31556410
131 + 31556279 = 31556410
167 + 31556243 = 31556410
269 + 31556141 = 31556410
311 + 31556099 = 31556410

Showing the first eight; more decompositions exist.
