Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552482, here are decompositions:

53 + 31552429 = 31552482
61 + 31552421 = 31552482
79 + 31552403 = 31552482
89 + 31552393 = 31552482
131 + 31552351 = 31552482
173 + 31552309 = 31552482
179 + 31552303 = 31552482
211 + 31552271 = 31552482

Showing the first eight; more decompositions exist.
