Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462764, here are decompositions:

5 + 31462759 = 31462764
7 + 31462757 = 31462764
13 + 31462751 = 31462764
17 + 31462747 = 31462764
41 + 31462723 = 31462764
173 + 31462591 = 31462764
181 + 31462583 = 31462764
191 + 31462573 = 31462764

Showing the first eight; more decompositions exist.
