Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603864, here are decompositions:

107 + 31603757 = 31603864
113 + 31603751 = 31603864
251 + 31603613 = 31603864
311 + 31603553 = 31603864
353 + 31603511 = 31603864
503 + 31603361 = 31603864
521 + 31603343 = 31603864
947 + 31602917 = 31603864

Showing the first eight; more decompositions exist.
