Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604070, here are decompositions:

13 + 31604057 = 31604070
19 + 31604051 = 31604070
37 + 31604033 = 31604070
79 + 31603991 = 31604070
83 + 31603987 = 31604070
137 + 31603933 = 31604070
139 + 31603931 = 31604070
151 + 31603919 = 31604070

Showing the first eight; more decompositions exist.
