Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604830, here are decompositions:

41 + 31604789 = 31604830
71 + 31604759 = 31604830
83 + 31604747 = 31604830
107 + 31604723 = 31604830
149 + 31604681 = 31604830
227 + 31604603 = 31604830
269 + 31604561 = 31604830
443 + 31604387 = 31604830

Showing the first eight; more decompositions exist.
