Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543702, here are decompositions:

5 + 31543697 = 31543702
11 + 31543691 = 31543702
41 + 31543661 = 31543702
59 + 31543643 = 31543702
131 + 31543571 = 31543702
173 + 31543529 = 31543702
251 + 31543451 = 31543702
353 + 31543349 = 31543702

Showing the first eight; more decompositions exist.
