Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604770, here are decompositions:

3 + 31604767 = 31604770
11 + 31604759 = 31604770
23 + 31604747 = 31604770
47 + 31604723 = 31604770
83 + 31604687 = 31604770
89 + 31604681 = 31604770
167 + 31604603 = 31604770
269 + 31604501 = 31604770

Showing the first eight; more decompositions exist.
