Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528424, here are decompositions:

61 + 31528363 = 31528424
97 + 31528327 = 31528424
157 + 31528267 = 31528424
211 + 31528213 = 31528424
313 + 31528111 = 31528424
331 + 31528093 = 31528424
457 + 31527967 = 31528424
607 + 31527817 = 31528424

Showing the first eight; more decompositions exist.
