Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527964, here are decompositions:

23 + 31527941 = 31527964
137 + 31527827 = 31527964
263 + 31527701 = 31527964
431 + 31527533 = 31527964
443 + 31527521 = 31527964
467 + 31527497 = 31527964
557 + 31527407 = 31527964
641 + 31527323 = 31527964

Showing the first eight; more decompositions exist.
