Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603846, here are decompositions:

3 + 31603843 = 31603846
17 + 31603829 = 31603846
89 + 31603757 = 31603846
107 + 31603739 = 31603846
137 + 31603709 = 31603846
233 + 31603613 = 31603846
269 + 31603577 = 31603846
293 + 31603553 = 31603846

Showing the first eight; more decompositions exist.
