Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542632, here are decompositions:

19 + 31542613 = 31542632
73 + 31542559 = 31542632
109 + 31542523 = 31542632
193 + 31542439 = 31542632
241 + 31542391 = 31542632
601 + 31542031 = 31542632
619 + 31542013 = 31542632
631 + 31542001 = 31542632

Showing the first eight; more decompositions exist.
