Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603850, here are decompositions:

7 + 31603843 = 31603850
139 + 31603711 = 31603850
193 + 31603657 = 31603850
241 + 31603609 = 31603850
283 + 31603567 = 31603850
331 + 31603519 = 31603850
457 + 31603393 = 31603850
541 + 31603309 = 31603850

Showing the first eight; more decompositions exist.
