Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603862, here are decompositions:

19 + 31603843 = 31603862
61 + 31603801 = 31603862
151 + 31603711 = 31603862
181 + 31603681 = 31603862
373 + 31603489 = 31603862
601 + 31603261 = 31603862
613 + 31603249 = 31603862
739 + 31603123 = 31603862

Showing the first eight; more decompositions exist.
