Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480282, here are decompositions:

23 + 31480259 = 31480282
179 + 31480103 = 31480282
191 + 31480091 = 31480282
233 + 31480049 = 31480282
263 + 31480019 = 31480282
401 + 31479881 = 31480282
461 + 31479821 = 31480282
479 + 31479803 = 31480282

Showing the first eight; more decompositions exist.
