Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445462, here are decompositions:

3 + 31445459 = 31445462
19 + 31445443 = 31445462
31 + 31445431 = 31445462
43 + 31445419 = 31445462
109 + 31445353 = 31445462
193 + 31445269 = 31445462
199 + 31445263 = 31445462
229 + 31445233 = 31445462

Showing the first eight; more decompositions exist.
