Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552410, here are decompositions:

7 + 31552403 = 31552410
17 + 31552393 = 31552410
23 + 31552387 = 31552410
59 + 31552351 = 31552410
101 + 31552309 = 31552410
107 + 31552303 = 31552410
139 + 31552271 = 31552410
157 + 31552253 = 31552410

Showing the first eight; more decompositions exist.
