Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543704, here are decompositions:

7 + 31543697 = 31543704
13 + 31543691 = 31543704
43 + 31543661 = 31543704
61 + 31543643 = 31543704
173 + 31543531 = 31543704
223 + 31543481 = 31543704
251 + 31543453 = 31543704
307 + 31543397 = 31543704

Showing the first eight; more decompositions exist.
