Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604028, here are decompositions:

37 + 31603991 = 31604028
41 + 31603987 = 31604028
97 + 31603931 = 31604028
109 + 31603919 = 31604028
139 + 31603889 = 31604028
149 + 31603879 = 31604028
151 + 31603877 = 31604028
199 + 31603829 = 31604028

Showing the first eight; more decompositions exist.
