Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484148, here are decompositions:

5 + 31484143 = 31484148
19 + 31484129 = 31484148
67 + 31484081 = 31484148
79 + 31484069 = 31484148
89 + 31484059 = 31484148
167 + 31483981 = 31484148
191 + 31483957 = 31484148
229 + 31483919 = 31484148

Showing the first eight; more decompositions exist.
