Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603626, here are decompositions:

13 + 31603613 = 31603626
17 + 31603609 = 31603626
59 + 31603567 = 31603626
73 + 31603553 = 31603626
107 + 31603519 = 31603626
137 + 31603489 = 31603626
139 + 31603487 = 31603626
199 + 31603427 = 31603626

Showing the first eight; more decompositions exist.
