Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542316, here are decompositions:

83 + 31542233 = 31542316
167 + 31542149 = 31542316
233 + 31542083 = 31542316
293 + 31542023 = 31542316
383 + 31541933 = 31542316
683 + 31541633 = 31542316
719 + 31541597 = 31542316
809 + 31541507 = 31542316

Showing the first eight; more decompositions exist.
