Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484018, here are decompositions:

37 + 31483981 = 31484018
61 + 31483957 = 31484018
157 + 31483861 = 31484018
199 + 31483819 = 31484018
211 + 31483807 = 31484018
229 + 31483789 = 31484018
421 + 31483597 = 31484018
547 + 31483471 = 31484018

Showing the first eight; more decompositions exist.
