Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530302, here are decompositions:

241 + 31530061 = 31530302
379 + 31529923 = 31530302
421 + 31529881 = 31530302
631 + 31529671 = 31530302
673 + 31529629 = 31530302
709 + 31529593 = 31530302
751 + 31529551 = 31530302
823 + 31529479 = 31530302

Showing the first eight; more decompositions exist.
