Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623248, here are decompositions:

37 + 31623211 = 31623248
67 + 31623181 = 31623248
79 + 31623169 = 31623248
127 + 31623121 = 31623248
367 + 31622881 = 31623248
439 + 31622809 = 31623248
577 + 31622671 = 31623248
607 + 31622641 = 31623248

Showing the first eight; more decompositions exist.
