Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623038, here are decompositions:

79 + 31622959 = 31623038
157 + 31622881 = 31623038
229 + 31622809 = 31623038
367 + 31622671 = 31623038
397 + 31622641 = 31623038
409 + 31622629 = 31623038
439 + 31622599 = 31623038
547 + 31622491 = 31623038

Showing the first eight; more decompositions exist.
