Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515762, here are decompositions:

29 + 31515733 = 31515762
43 + 31515719 = 31515762
59 + 31515703 = 31515762
79 + 31515683 = 31515762
151 + 31515611 = 31515762
163 + 31515599 = 31515762
199 + 31515563 = 31515762
349 + 31515413 = 31515762

Showing the first eight; more decompositions exist.
