Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628104, here are decompositions:

3 + 31628101 = 31628104
5 + 31628099 = 31628104
83 + 31628021 = 31628104
173 + 31627931 = 31628104
293 + 31627811 = 31628104
311 + 31627793 = 31628104
353 + 31627751 = 31628104
383 + 31627721 = 31628104

Showing the first eight; more decompositions exist.
