Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445464, here are decompositions:

5 + 31445459 = 31445464
47 + 31445417 = 31445464
107 + 31445357 = 31445464
191 + 31445273 = 31445464
233 + 31445231 = 31445464
263 + 31445201 = 31445464
353 + 31445111 = 31445464
431 + 31445033 = 31445464

Showing the first eight; more decompositions exist.
