Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543608, here are decompositions:

29 + 31543579 = 31543608
37 + 31543571 = 31543608
79 + 31543529 = 31543608
127 + 31543481 = 31543608
157 + 31543451 = 31543608
179 + 31543429 = 31543608
211 + 31543397 = 31543608
277 + 31543331 = 31543608

Showing the first eight; more decompositions exist.
