Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562462, here are decompositions:

13 + 31562449 = 31562462
31 + 31562431 = 31562462
73 + 31562389 = 31562462
163 + 31562299 = 31562462
181 + 31562281 = 31562462
199 + 31562263 = 31562462
409 + 31562053 = 31562462
439 + 31562023 = 31562462

Showing the first eight; more decompositions exist.
