Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603234, here are decompositions:

41 + 31603193 = 31603234
317 + 31602917 = 31603234
431 + 31602803 = 31603234
587 + 31602647 = 31603234
647 + 31602587 = 31603234
653 + 31602581 = 31603234
881 + 31602353 = 31603234
911 + 31602323 = 31603234

Showing the first eight; more decompositions exist.
