Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484138, here are decompositions:

67 + 31484071 = 31484138
79 + 31484059 = 31484138
157 + 31483981 = 31484138
181 + 31483957 = 31484138
211 + 31483927 = 31484138
277 + 31483861 = 31484138
331 + 31483807 = 31484138
337 + 31483801 = 31484138

Showing the first eight; more decompositions exist.
