Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603910, here are decompositions:

31 + 31603879 = 31603910
67 + 31603843 = 31603910
109 + 31603801 = 31603910
193 + 31603717 = 31603910
199 + 31603711 = 31603910
229 + 31603681 = 31603910
421 + 31603489 = 31603910
601 + 31603309 = 31603910

Showing the first eight; more decompositions exist.
