Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603652, here are decompositions:

43 + 31603609 = 31603652
163 + 31603489 = 31603652
271 + 31603381 = 31603652
541 + 31603111 = 31603652
643 + 31603009 = 31603652
859 + 31602793 = 31603652
991 + 31602661 = 31603652
1021 + 31602631 = 31603652

Showing the first eight; more decompositions exist.
