Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552586, here are decompositions:

7 + 31552579 = 31552586
97 + 31552489 = 31552586
157 + 31552429 = 31552586
193 + 31552393 = 31552586
199 + 31552387 = 31552586
277 + 31552309 = 31552586
283 + 31552303 = 31552586
349 + 31552237 = 31552586

Showing the first eight; more decompositions exist.
