Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527988, here are decompositions:

47 + 31527941 = 31527988
101 + 31527887 = 31527988
311 + 31527677 = 31527988
419 + 31527569 = 31527988
467 + 31527521 = 31527988
491 + 31527497 = 31527988
599 + 31527389 = 31527988
677 + 31527311 = 31527988

Showing the first eight; more decompositions exist.
