Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603436, here are decompositions:

43 + 31603393 = 31603436
127 + 31603309 = 31603436
313 + 31603123 = 31603436
409 + 31603027 = 31603436
463 + 31602973 = 31603436
577 + 31602859 = 31603436
643 + 31602793 = 31603436
673 + 31602763 = 31603436

Showing the first eight; more decompositions exist.
