Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603702, here are decompositions:

59 + 31603643 = 31603702
89 + 31603613 = 31603702
149 + 31603553 = 31603702
191 + 31603511 = 31603702
359 + 31603343 = 31603702
443 + 31603259 = 31603702
509 + 31603193 = 31603702
563 + 31603139 = 31603702

Showing the first eight; more decompositions exist.
