Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496772, here are decompositions:

31 + 31496741 = 31496772
53 + 31496719 = 31496772
79 + 31496693 = 31496772
101 + 31496671 = 31496772
103 + 31496669 = 31496772
173 + 31496599 = 31496772
179 + 31496593 = 31496772
199 + 31496573 = 31496772

Showing the first eight; more decompositions exist.
