Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544338, here are decompositions:

41 + 31544297 = 31544338
131 + 31544207 = 31544338
149 + 31544189 = 31544338
167 + 31544171 = 31544338
239 + 31544099 = 31544338
281 + 31544057 = 31544338
317 + 31544021 = 31544338
347 + 31543991 = 31544338

Showing the first eight; more decompositions exist.
