Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534274, here are decompositions:

3 + 31534271 = 31534274
43 + 31534231 = 31534274
157 + 31534117 = 31534274
223 + 31534051 = 31534274
241 + 31534033 = 31534274
307 + 31533967 = 31534274
613 + 31533661 = 31534274
643 + 31533631 = 31534274

Showing the first eight; more decompositions exist.
