Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628348, here are decompositions:

7 + 31628341 = 31628348
79 + 31628269 = 31628348
109 + 31628239 = 31628348
181 + 31628167 = 31628348
331 + 31628017 = 31628348
337 + 31628011 = 31628348
379 + 31627969 = 31628348
421 + 31627927 = 31628348

Showing the first eight; more decompositions exist.
