Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496718, here are decompositions:

41 + 31496677 = 31496718
47 + 31496671 = 31496718
107 + 31496611 = 31496718
131 + 31496587 = 31496718
151 + 31496567 = 31496718
167 + 31496551 = 31496718
179 + 31496539 = 31496718
181 + 31496537 = 31496718

Showing the first eight; more decompositions exist.
