Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544038, here are decompositions:

5 + 31544033 = 31544038
17 + 31544021 = 31544038
41 + 31543997 = 31544038
47 + 31543991 = 31544038
59 + 31543979 = 31544038
131 + 31543907 = 31544038
167 + 31543871 = 31544038
179 + 31543859 = 31544038

Showing the first eight; more decompositions exist.
