Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464044, here are decompositions:

13 + 31464031 = 31464044
43 + 31464001 = 31464044
103 + 31463941 = 31464044
151 + 31463893 = 31464044
277 + 31463767 = 31464044
331 + 31463713 = 31464044
457 + 31463587 = 31464044
691 + 31463353 = 31464044

Showing the first eight; more decompositions exist.
