Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551526, here are decompositions:

23 + 31551503 = 31551526
29 + 31551497 = 31551526
89 + 31551437 = 31551526
113 + 31551413 = 31551526
173 + 31551353 = 31551526
179 + 31551347 = 31551526
197 + 31551329 = 31551526
353 + 31551173 = 31551526

Showing the first eight; more decompositions exist.
