Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496802, here are decompositions:

11 + 31496791 = 31496802
19 + 31496783 = 31496802
23 + 31496779 = 31496802
61 + 31496741 = 31496802
83 + 31496719 = 31496802
109 + 31496693 = 31496802
131 + 31496671 = 31496802
191 + 31496611 = 31496802

Showing the first eight; more decompositions exist.
