Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496760, here are decompositions:

19 + 31496741 = 31496760
41 + 31496719 = 31496760
67 + 31496693 = 31496760
83 + 31496677 = 31496760
89 + 31496671 = 31496760
149 + 31496611 = 31496760
167 + 31496593 = 31496760
173 + 31496587 = 31496760

Showing the first eight; more decompositions exist.
