Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628174, here are decompositions:

3 + 31628171 = 31628174
7 + 31628167 = 31628174
13 + 31628161 = 31628174
73 + 31628101 = 31628174
157 + 31628017 = 31628174
163 + 31628011 = 31628174
271 + 31627903 = 31628174
313 + 31627861 = 31628174

Showing the first eight; more decompositions exist.
