Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544298, here are decompositions:

17 + 31544281 = 31544298
109 + 31544189 = 31544298
127 + 31544171 = 31544298
131 + 31544167 = 31544298
167 + 31544131 = 31544298
199 + 31544099 = 31544298
241 + 31544057 = 31544298
257 + 31544041 = 31544298

Showing the first eight; more decompositions exist.
