Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542614, here are decompositions:

67 + 31542547 = 31542614
127 + 31542487 = 31542614
157 + 31542457 = 31542614
223 + 31542391 = 31542614
241 + 31542373 = 31542614
547 + 31542067 = 31542614
577 + 31542037 = 31542614
601 + 31542013 = 31542614

Showing the first eight; more decompositions exist.
