Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550562, here are decompositions:

5 + 31550557 = 31550562
19 + 31550543 = 31550562
23 + 31550539 = 31550562
31 + 31550531 = 31550562
53 + 31550509 = 31550562
83 + 31550479 = 31550562
101 + 31550461 = 31550562
103 + 31550459 = 31550562

Showing the first eight; more decompositions exist.
