Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603776, here are decompositions:

19 + 31603757 = 31603776
37 + 31603739 = 31603776
59 + 31603717 = 31603776
67 + 31603709 = 31603776
163 + 31603613 = 31603776
167 + 31603609 = 31603776
199 + 31603577 = 31603776
223 + 31603553 = 31603776

Showing the first eight; more decompositions exist.
