Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468044, here are decompositions:

17 + 31468027 = 31468044
31 + 31468013 = 31468044
43 + 31468001 = 31468044
61 + 31467983 = 31468044
107 + 31467937 = 31468044
151 + 31467893 = 31468044
191 + 31467853 = 31468044
197 + 31467847 = 31468044

Showing the first eight; more decompositions exist.
