Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544088, here are decompositions:

11 + 31544077 = 31544088
31 + 31544057 = 31544088
47 + 31544041 = 31544088
67 + 31544021 = 31544088
97 + 31543991 = 31544088
101 + 31543987 = 31544088
109 + 31543979 = 31544088
127 + 31543961 = 31544088

Showing the first eight; more decompositions exist.
