Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628054, here are decompositions:

37 + 31628017 = 31628054
43 + 31628011 = 31628054
127 + 31627927 = 31628054
151 + 31627903 = 31628054
193 + 31627861 = 31628054
487 + 31627567 = 31628054
571 + 31627483 = 31628054
643 + 31627411 = 31628054

Showing the first eight; more decompositions exist.
