Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539622, here are decompositions:

29 + 31539593 = 31539622
53 + 31539569 = 31539622
269 + 31539353 = 31539622
293 + 31539329 = 31539622
431 + 31539191 = 31539622
479 + 31539143 = 31539622
911 + 31538711 = 31539622
929 + 31538693 = 31539622

Showing the first eight; more decompositions exist.
