Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489044, here are decompositions:

7 + 31489037 = 31489044
17 + 31489027 = 31489044
53 + 31488991 = 31489044
73 + 31488971 = 31489044
113 + 31488931 = 31489044
127 + 31488917 = 31489044
137 + 31488907 = 31489044
277 + 31488767 = 31489044

Showing the first eight; more decompositions exist.
