Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482618, here are decompositions:

5 + 31482613 = 31482618
19 + 31482599 = 31482618
31 + 31482587 = 31482618
59 + 31482559 = 31482618
67 + 31482551 = 31482618
107 + 31482511 = 31482618
109 + 31482509 = 31482618
179 + 31482439 = 31482618

Showing the first eight; more decompositions exist.
