Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552466, here are decompositions:

37 + 31552429 = 31552466
73 + 31552393 = 31552466
79 + 31552387 = 31552466
157 + 31552309 = 31552466
163 + 31552303 = 31552466
229 + 31552237 = 31552466
397 + 31552069 = 31552466
409 + 31552057 = 31552466

Showing the first eight; more decompositions exist.
