Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544074, here are decompositions:

17 + 31544057 = 31544074
41 + 31544033 = 31544074
53 + 31544021 = 31544074
83 + 31543991 = 31544074
113 + 31543961 = 31544074
167 + 31543907 = 31544074
197 + 31543877 = 31544074
227 + 31543847 = 31544074

Showing the first eight; more decompositions exist.
