Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480570, here are decompositions:

41 + 31480529 = 31480570
137 + 31480433 = 31480570
179 + 31480391 = 31480570
197 + 31480373 = 31480570
281 + 31480289 = 31480570
311 + 31480259 = 31480570
467 + 31480103 = 31480570
479 + 31480091 = 31480570

Showing the first eight; more decompositions exist.
