Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556698, here are decompositions:

11 + 31556687 = 31556698
59 + 31556639 = 31556698
197 + 31556501 = 31556698
281 + 31556417 = 31556698
317 + 31556381 = 31556698
389 + 31556309 = 31556698
419 + 31556279 = 31556698
449 + 31556249 = 31556698

Showing the first eight; more decompositions exist.
