Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543796, here are decompositions:

13 + 31543783 = 31543796
19 + 31543777 = 31543796
73 + 31543723 = 31543796
127 + 31543669 = 31543796
307 + 31543489 = 31543796
367 + 31543429 = 31543796
523 + 31543273 = 31543796
577 + 31543219 = 31543796

Showing the first eight; more decompositions exist.
