Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484234, here are decompositions:

31 + 31484203 = 31484234
73 + 31484161 = 31484234
163 + 31484071 = 31484234
277 + 31483957 = 31484234
307 + 31483927 = 31484234
373 + 31483861 = 31484234
433 + 31483801 = 31484234
571 + 31483663 = 31484234

Showing the first eight; more decompositions exist.
