Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453636, here are decompositions:

59 + 31453577 = 31453636
107 + 31453529 = 31453636
113 + 31453523 = 31453636
173 + 31453463 = 31453636
353 + 31453283 = 31453636
443 + 31453193 = 31453636
479 + 31453157 = 31453636
503 + 31453133 = 31453636

Showing the first eight; more decompositions exist.
