Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543276, here are decompositions:

3 + 31543273 = 31543276
53 + 31543223 = 31543276
59 + 31543217 = 31543276
113 + 31543163 = 31543276
173 + 31543103 = 31543276
197 + 31543079 = 31543276
257 + 31543019 = 31543276
419 + 31542857 = 31543276

Showing the first eight; more decompositions exist.
