Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604026, here are decompositions:

107 + 31603919 = 31604026
137 + 31603889 = 31604026
149 + 31603877 = 31604026
197 + 31603829 = 31604026
269 + 31603757 = 31604026
317 + 31603709 = 31604026
383 + 31603643 = 31604026
449 + 31603577 = 31604026

Showing the first eight; more decompositions exist.
