Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603924, here are decompositions:

5 + 31603919 = 31603924
47 + 31603877 = 31603924
167 + 31603757 = 31603924
173 + 31603751 = 31603924
281 + 31603643 = 31603924
311 + 31603613 = 31603924
347 + 31603577 = 31603924
557 + 31603367 = 31603924

Showing the first eight; more decompositions exist.
