Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15764, here are decompositions:

3 + 15761 = 15764
31 + 15733 = 15764
37 + 15727 = 15764
97 + 15667 = 15764
103 + 15661 = 15764
157 + 15607 = 15764
163 + 15601 = 15764
181 + 15583 = 15764

Showing the first eight; more decompositions exist.
