Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628336, here are decompositions:

67 + 31628269 = 31628336
97 + 31628239 = 31628336
163 + 31628173 = 31628336
367 + 31627969 = 31628336
409 + 31627927 = 31628336
433 + 31627903 = 31628336
457 + 31627879 = 31628336
709 + 31627627 = 31628336

Showing the first eight; more decompositions exist.
