Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603076, here are decompositions:

3 + 31603073 = 31603076
67 + 31603009 = 31603076
103 + 31602973 = 31603076
199 + 31602877 = 31603076
223 + 31602853 = 31603076
283 + 31602793 = 31603076
313 + 31602763 = 31603076
397 + 31602679 = 31603076

Showing the first eight; more decompositions exist.
