Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603726, here are decompositions:

5 + 31603721 = 31603726
17 + 31603709 = 31603726
83 + 31603643 = 31603726
113 + 31603613 = 31603726
149 + 31603577 = 31603726
173 + 31603553 = 31603726
239 + 31603487 = 31603726
359 + 31603367 = 31603726

Showing the first eight; more decompositions exist.
