Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527904, here are decompositions:

17 + 31527887 = 31527904
227 + 31527677 = 31527904
383 + 31527521 = 31527904
491 + 31527413 = 31527904
587 + 31527317 = 31527904
593 + 31527311 = 31527904
761 + 31527143 = 31527904
773 + 31527131 = 31527904

Showing the first eight; more decompositions exist.
