Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552476, here are decompositions:

47 + 31552429 = 31552476
73 + 31552403 = 31552476
83 + 31552393 = 31552476
89 + 31552387 = 31552476
167 + 31552309 = 31552476
173 + 31552303 = 31552476
223 + 31552253 = 31552476
239 + 31552237 = 31552476

Showing the first eight; more decompositions exist.
