Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542664, here are decompositions:

5 + 31542659 = 31542664
227 + 31542437 = 31542664
383 + 31542281 = 31542664
431 + 31542233 = 31542664
467 + 31542197 = 31542664
641 + 31542023 = 31542664
653 + 31542011 = 31542664
683 + 31541981 = 31542664

Showing the first eight; more decompositions exist.
