Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553696, here are decompositions:

37 + 31553659 = 31553696
79 + 31553617 = 31553696
193 + 31553503 = 31553696
313 + 31553383 = 31553696
337 + 31553359 = 31553696
463 + 31553233 = 31553696
607 + 31553089 = 31553696
619 + 31553077 = 31553696

Showing the first eight; more decompositions exist.
