Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518734, here are decompositions:

43 + 31518691 = 31518734
61 + 31518673 = 31518734
127 + 31518607 = 31518734
193 + 31518541 = 31518734
211 + 31518523 = 31518734
277 + 31518457 = 31518734
283 + 31518451 = 31518734
307 + 31518427 = 31518734

Showing the first eight; more decompositions exist.
