Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603526, here are decompositions:

7 + 31603519 = 31603526
37 + 31603489 = 31603526
277 + 31603249 = 31603526
379 + 31603147 = 31603526
499 + 31603027 = 31603526
673 + 31602853 = 31603526
733 + 31602793 = 31603526
853 + 31602673 = 31603526

Showing the first eight; more decompositions exist.
