Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552634, here are decompositions:

13 + 31552621 = 31552634
31 + 31552603 = 31552634
97 + 31552537 = 31552634
241 + 31552393 = 31552634
283 + 31552351 = 31552634
331 + 31552303 = 31552634
397 + 31552237 = 31552634
577 + 31552057 = 31552634

Showing the first eight; more decompositions exist.
