Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530254, here are decompositions:

43 + 31530211 = 31530254
73 + 31530181 = 31530254
157 + 31530097 = 31530254
193 + 31530061 = 31530254
211 + 31530043 = 31530254
277 + 31529977 = 31530254
331 + 31529923 = 31530254
373 + 31529881 = 31530254

Showing the first eight; more decompositions exist.
