Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603888, here are decompositions:

11 + 31603877 = 31603888
59 + 31603829 = 31603888
131 + 31603757 = 31603888
137 + 31603751 = 31603888
149 + 31603739 = 31603888
167 + 31603721 = 31603888
179 + 31603709 = 31603888
311 + 31603577 = 31603888

Showing the first eight; more decompositions exist.
