Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628276, here are decompositions:

3 + 31628273 = 31628276
7 + 31628269 = 31628276
37 + 31628239 = 31628276
103 + 31628173 = 31628276
109 + 31628167 = 31628276
307 + 31627969 = 31628276
349 + 31627927 = 31628276
373 + 31627903 = 31628276

Showing the first eight; more decompositions exist.
