Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530246, here are decompositions:

43 + 31530203 = 31530246
73 + 31530173 = 31530246
103 + 31530143 = 31530246
149 + 31530097 = 31530246
229 + 31530017 = 31530246
269 + 31529977 = 31530246
277 + 31529969 = 31530246
313 + 31529933 = 31530246

Showing the first eight; more decompositions exist.
