Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482462, here are decompositions:

23 + 31482439 = 31482462
61 + 31482401 = 31482462
73 + 31482389 = 31482462
113 + 31482349 = 31482462
181 + 31482281 = 31482462
191 + 31482271 = 31482462
233 + 31482229 = 31482462
283 + 31482179 = 31482462

Showing the first eight; more decompositions exist.
