Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544122, here are decompositions:

23 + 31544099 = 31544122
83 + 31544039 = 31544122
89 + 31544033 = 31544122
101 + 31544021 = 31544122
131 + 31543991 = 31544122
251 + 31543871 = 31544122
263 + 31543859 = 31544122
293 + 31543829 = 31544122

Showing the first eight; more decompositions exist.
