Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544154, here are decompositions:

23 + 31544131 = 31544154
97 + 31544057 = 31544154
101 + 31544053 = 31544154
113 + 31544041 = 31544154
157 + 31543997 = 31544154
163 + 31543991 = 31544154
167 + 31543987 = 31544154
193 + 31543961 = 31544154

Showing the first eight; more decompositions exist.
