Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604194, here are decompositions:

3 + 31604191 = 31604194
5 + 31604189 = 31604194
137 + 31604057 = 31604194
263 + 31603931 = 31604194
317 + 31603877 = 31604194
443 + 31603751 = 31604194
617 + 31603577 = 31604194
641 + 31603553 = 31604194

Showing the first eight; more decompositions exist.
