Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603710, here are decompositions:

29 + 31603681 = 31603710
53 + 31603657 = 31603710
67 + 31603643 = 31603710
97 + 31603613 = 31603710
101 + 31603609 = 31603710
157 + 31603553 = 31603710
191 + 31603519 = 31603710
199 + 31603511 = 31603710

Showing the first eight; more decompositions exist.
