Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480566, here are decompositions:

37 + 31480529 = 31480566
59 + 31480507 = 31480566
193 + 31480373 = 31480566
197 + 31480369 = 31480566
199 + 31480367 = 31480566
277 + 31480289 = 31480566
307 + 31480259 = 31480566
449 + 31480117 = 31480566

Showing the first eight; more decompositions exist.
