Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604038, here are decompositions:

5 + 31604033 = 31604038
47 + 31603991 = 31604038
107 + 31603931 = 31604038
149 + 31603889 = 31604038
281 + 31603757 = 31604038
317 + 31603721 = 31604038
461 + 31603577 = 31604038
677 + 31603361 = 31604038

Showing the first eight; more decompositions exist.
