Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603174, here are decompositions:

17 + 31603157 = 31603174
101 + 31603073 = 31603174
257 + 31602917 = 31603174
311 + 31602863 = 31603174
587 + 31602587 = 31603174
593 + 31602581 = 31603174
653 + 31602521 = 31603174
677 + 31602497 = 31603174

Showing the first eight; more decompositions exist.
