Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542416, here are decompositions:

19 + 31542397 = 31542416
43 + 31542373 = 31542416
313 + 31542103 = 31542416
349 + 31542067 = 31542416
379 + 31542037 = 31542416
439 + 31541977 = 31542416
523 + 31541893 = 31542416
547 + 31541869 = 31542416

Showing the first eight; more decompositions exist.
