Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623008, here are decompositions:

61 + 31622947 = 31623008
127 + 31622881 = 31623008
199 + 31622809 = 31623008
229 + 31622779 = 31623008
337 + 31622671 = 31623008
367 + 31622641 = 31623008
379 + 31622629 = 31623008
409 + 31622599 = 31623008

Showing the first eight; more decompositions exist.
