Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603650, here are decompositions:

7 + 31603643 = 31603650
37 + 31603613 = 31603650
41 + 31603609 = 31603650
73 + 31603577 = 31603650
83 + 31603567 = 31603650
97 + 31603553 = 31603650
131 + 31603519 = 31603650
139 + 31603511 = 31603650

Showing the first eight; more decompositions exist.
