Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543710, here are decompositions:

13 + 31543697 = 31543710
19 + 31543691 = 31543710
41 + 31543669 = 31543710
67 + 31543643 = 31543710
131 + 31543579 = 31543710
139 + 31543571 = 31543710
167 + 31543543 = 31543710
179 + 31543531 = 31543710

Showing the first eight; more decompositions exist.
