Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628048, here are decompositions:

31 + 31628017 = 31628048
37 + 31628011 = 31628048
79 + 31627969 = 31628048
409 + 31627639 = 31628048
421 + 31627627 = 31628048
547 + 31627501 = 31628048
691 + 31627357 = 31628048
787 + 31627261 = 31628048

Showing the first eight; more decompositions exist.
