Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484118, here are decompositions:

37 + 31484081 = 31484118
47 + 31484071 = 31484118
59 + 31484059 = 31484118
137 + 31483981 = 31484118
139 + 31483979 = 31484118
191 + 31483927 = 31484118
199 + 31483919 = 31484118
229 + 31483889 = 31484118

Showing the first eight; more decompositions exist.
