Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603994, here are decompositions:

3 + 31603991 = 31603994
7 + 31603987 = 31603994
61 + 31603933 = 31603994
151 + 31603843 = 31603994
193 + 31603801 = 31603994
277 + 31603717 = 31603994
283 + 31603711 = 31603994
313 + 31603681 = 31603994

Showing the first eight; more decompositions exist.
