Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528648, here are decompositions:

89 + 31528559 = 31528648
101 + 31528547 = 31528648
149 + 31528499 = 31528648
197 + 31528451 = 31528648
311 + 31528337 = 31528648
419 + 31528229 = 31528648
479 + 31528169 = 31528648
491 + 31528157 = 31528648

Showing the first eight; more decompositions exist.
