Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604206, here are decompositions:

17 + 31604189 = 31604206
107 + 31604099 = 31604206
149 + 31604057 = 31604206
173 + 31604033 = 31604206
317 + 31603889 = 31604206
449 + 31603757 = 31604206
467 + 31603739 = 31604206
563 + 31603643 = 31604206

Showing the first eight; more decompositions exist.
