Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603996, here are decompositions:

5 + 31603991 = 31603996
107 + 31603889 = 31603996
167 + 31603829 = 31603996
239 + 31603757 = 31603996
257 + 31603739 = 31603996
353 + 31603643 = 31603996
383 + 31603613 = 31603996
419 + 31603577 = 31603996

Showing the first eight; more decompositions exist.
