Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546942, here are decompositions:

5 + 31546937 = 31546942
29 + 31546913 = 31546942
233 + 31546709 = 31546942
281 + 31546661 = 31546942
359 + 31546583 = 31546942
389 + 31546553 = 31546942
491 + 31546451 = 31546942
521 + 31546421 = 31546942

Showing the first eight; more decompositions exist.
