Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603226, here are decompositions:

79 + 31603147 = 31603226
103 + 31603123 = 31603226
199 + 31603027 = 31603226
349 + 31602877 = 31603226
367 + 31602859 = 31603226
373 + 31602853 = 31603226
433 + 31602793 = 31603226
463 + 31602763 = 31603226

Showing the first eight; more decompositions exist.
