Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628294, here are decompositions:

3 + 31628291 = 31628294
127 + 31628167 = 31628294
193 + 31628101 = 31628294
277 + 31628017 = 31628294
283 + 31628011 = 31628294
367 + 31627927 = 31628294
433 + 31627861 = 31628294
541 + 31627753 = 31628294

Showing the first eight; more decompositions exist.
