Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528604, here are decompositions:

31 + 31528573 = 31528604
73 + 31528531 = 31528604
103 + 31528501 = 31528604
157 + 31528447 = 31528604
241 + 31528363 = 31528604
277 + 31528327 = 31528604
313 + 31528291 = 31528604
337 + 31528267 = 31528604

Showing the first eight; more decompositions exist.
