Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544118, here are decompositions:

19 + 31544099 = 31544118
29 + 31544089 = 31544118
41 + 31544077 = 31544118
61 + 31544057 = 31544118
79 + 31544039 = 31544118
97 + 31544021 = 31544118
107 + 31544011 = 31544118
127 + 31543991 = 31544118

Showing the first eight; more decompositions exist.
