Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543844, here are decompositions:

61 + 31543783 = 31543844
67 + 31543777 = 31543844
313 + 31543531 = 31543844
571 + 31543273 = 31543844
601 + 31543243 = 31543844
613 + 31543231 = 31543844
853 + 31542991 = 31543844
877 + 31542967 = 31543844

Showing the first eight; more decompositions exist.
