Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603424, here are decompositions:

31 + 31603393 = 31603424
43 + 31603381 = 31603424
163 + 31603261 = 31603424
277 + 31603147 = 31603424
283 + 31603141 = 31603424
313 + 31603111 = 31603424
397 + 31603027 = 31603424
547 + 31602877 = 31603424

Showing the first eight; more decompositions exist.
