Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463620, here are decompositions:

29 + 31463591 = 31463620
101 + 31463519 = 31463620
113 + 31463507 = 31463620
131 + 31463489 = 31463620
137 + 31463483 = 31463620
191 + 31463429 = 31463620
233 + 31463387 = 31463620
257 + 31463363 = 31463620

Showing the first eight; more decompositions exist.
