Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544274, here are decompositions:

53 + 31544221 = 31544274
61 + 31544213 = 31544274
67 + 31544207 = 31544274
103 + 31544171 = 31544274
107 + 31544167 = 31544274
197 + 31544077 = 31544274
233 + 31544041 = 31544274
241 + 31544033 = 31544274

Showing the first eight; more decompositions exist.
