Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628012, here are decompositions:

43 + 31627969 = 31628012
109 + 31627903 = 31628012
151 + 31627861 = 31628012
211 + 31627801 = 31628012
373 + 31627639 = 31628012
439 + 31627573 = 31628012
601 + 31627411 = 31628012
709 + 31627303 = 31628012

Showing the first eight; more decompositions exist.
