Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530294, here are decompositions:

83 + 31530211 = 31530294
97 + 31530197 = 31530294
113 + 31530181 = 31530294
151 + 31530143 = 31530294
197 + 31530097 = 31530294
233 + 31530061 = 31530294
251 + 31530043 = 31530294
277 + 31530017 = 31530294

Showing the first eight; more decompositions exist.
