Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604020, here are decompositions:

29 + 31603991 = 31604020
89 + 31603931 = 31604020
101 + 31603919 = 31604020
131 + 31603889 = 31604020
191 + 31603829 = 31604020
263 + 31603757 = 31604020
269 + 31603751 = 31604020
281 + 31603739 = 31604020

Showing the first eight; more decompositions exist.
