Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548632, here are decompositions:

13 + 31548619 = 31548632
19 + 31548613 = 31548632
331 + 31548301 = 31548632
499 + 31548133 = 31548632
523 + 31548109 = 31548632
601 + 31548031 = 31548632
673 + 31547959 = 31548632
883 + 31547749 = 31548632

Showing the first eight; more decompositions exist.
