Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604692, here are decompositions:

3 + 31604689 = 31604692
5 + 31604687 = 31604692
11 + 31604681 = 31604692
83 + 31604609 = 31604692
89 + 31604603 = 31604692
131 + 31604561 = 31604692
191 + 31604501 = 31604692
239 + 31604453 = 31604692

Showing the first eight; more decompositions exist.
