Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452616, here are decompositions:

17 + 31452599 = 31452616
29 + 31452587 = 31452616
89 + 31452527 = 31452616
197 + 31452419 = 31452616
383 + 31452233 = 31452616
443 + 31452173 = 31452616
479 + 31452137 = 31452616
617 + 31451999 = 31452616

Showing the first eight; more decompositions exist.
