Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530338, here are decompositions:

127 + 31530211 = 31530338
157 + 31530181 = 31530338
241 + 31530097 = 31530338
277 + 31530061 = 31530338
337 + 31530001 = 31530338
439 + 31529899 = 31530338
457 + 31529881 = 31530338
661 + 31529677 = 31530338

Showing the first eight; more decompositions exist.
