Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480596, here are decompositions:

67 + 31480529 = 31480596
89 + 31480507 = 31480596
163 + 31480433 = 31480596
223 + 31480373 = 31480596
227 + 31480369 = 31480596
229 + 31480367 = 31480596
307 + 31480289 = 31480596
337 + 31480259 = 31480596

Showing the first eight; more decompositions exist.
