Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480426, here are decompositions:

53 + 31480373 = 31480426
59 + 31480367 = 31480426
137 + 31480289 = 31480426
167 + 31480259 = 31480426
347 + 31480079 = 31480426
479 + 31479947 = 31480426
569 + 31479857 = 31480426
683 + 31479743 = 31480426

Showing the first eight; more decompositions exist.
