Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496738, here are decompositions:

19 + 31496719 = 31496738
61 + 31496677 = 31496738
67 + 31496671 = 31496738
127 + 31496611 = 31496738
139 + 31496599 = 31496738
151 + 31496587 = 31496738
199 + 31496539 = 31496738
349 + 31496389 = 31496738

Showing the first eight; more decompositions exist.
