Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544152, here are decompositions:

53 + 31544099 = 31544152
113 + 31544039 = 31544152
131 + 31544021 = 31544152
173 + 31543979 = 31544152
191 + 31543961 = 31544152
239 + 31543913 = 31544152
281 + 31543871 = 31544152
293 + 31543859 = 31544152

Showing the first eight; more decompositions exist.
