Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445044, here are decompositions:

3 + 31445041 = 31445044
11 + 31445033 = 31445044
17 + 31445027 = 31445044
107 + 31444937 = 31445044
167 + 31444877 = 31445044
173 + 31444871 = 31445044
317 + 31444727 = 31445044
353 + 31444691 = 31445044

Showing the first eight; more decompositions exist.
