Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603012, here are decompositions:

3 + 31603009 = 31603012
53 + 31602959 = 31603012
113 + 31602899 = 31603012
149 + 31602863 = 31603012
431 + 31602581 = 31603012
491 + 31602521 = 31603012
569 + 31602443 = 31603012
659 + 31602353 = 31603012

Showing the first eight; more decompositions exist.
