Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603046, here are decompositions:

19 + 31603027 = 31603046
37 + 31603009 = 31603046
73 + 31602973 = 31603046
193 + 31602853 = 31603046
283 + 31602763 = 31603046
367 + 31602679 = 31603046
373 + 31602673 = 31603046
457 + 31602589 = 31603046

Showing the first eight; more decompositions exist.
