Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567562, here are decompositions:

3 + 31567559 = 31567562
151 + 31567411 = 31567562
193 + 31567369 = 31567562
283 + 31567279 = 31567562
331 + 31567231 = 31567562
349 + 31567213 = 31567562
409 + 31567153 = 31567562
643 + 31566919 = 31567562

Showing the first eight; more decompositions exist.
