Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603294, here are decompositions:

101 + 31603193 = 31603294
137 + 31603157 = 31603294
431 + 31602863 = 31603294
491 + 31602803 = 31603294
647 + 31602647 = 31603294
773 + 31602521 = 31603294
797 + 31602497 = 31603294
941 + 31602353 = 31603294

Showing the first eight; more decompositions exist.
