Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552554, here are decompositions:

17 + 31552537 = 31552554
67 + 31552487 = 31552554
151 + 31552403 = 31552554
167 + 31552387 = 31552554
251 + 31552303 = 31552554
283 + 31552271 = 31552554
317 + 31552237 = 31552554
347 + 31552207 = 31552554

Showing the first eight; more decompositions exist.
