Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548618, here are decompositions:

5 + 31548613 = 31548618
41 + 31548577 = 31548618
67 + 31548551 = 31548618
71 + 31548547 = 31548618
97 + 31548521 = 31548618
151 + 31548467 = 31548618
191 + 31548427 = 31548618
317 + 31548301 = 31548618

Showing the first eight; more decompositions exist.
