Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484262, here are decompositions:

23 + 31484239 = 31484262
53 + 31484209 = 31484262
59 + 31484203 = 31484262
83 + 31484179 = 31484262
101 + 31484161 = 31484262
181 + 31484081 = 31484262
191 + 31484071 = 31484262
193 + 31484069 = 31484262

Showing the first eight; more decompositions exist.
