Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506848, here are decompositions:

7 + 31506841 = 31506848
19 + 31506829 = 31506848
67 + 31506781 = 31506848
151 + 31506697 = 31506848
271 + 31506577 = 31506848
337 + 31506511 = 31506848
577 + 31506271 = 31506848
601 + 31506247 = 31506848

Showing the first eight; more decompositions exist.
