Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628246, here are decompositions:

7 + 31628239 = 31628246
73 + 31628173 = 31628246
79 + 31628167 = 31628246
157 + 31628089 = 31628246
229 + 31628017 = 31628246
277 + 31627969 = 31628246
367 + 31627879 = 31628246
607 + 31627639 = 31628246

Showing the first eight; more decompositions exist.
