Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528484, here are decompositions:

37 + 31528447 = 31528484
157 + 31528327 = 31528484
193 + 31528291 = 31528484
271 + 31528213 = 31528484
277 + 31528207 = 31528484
313 + 31528171 = 31528484
373 + 31528111 = 31528484
487 + 31527997 = 31528484

Showing the first eight; more decompositions exist.
