Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722174, here are decompositions:

3 + 8722171 = 8722174
5 + 8722169 = 8722174
173 + 8722001 = 8722174
233 + 8721941 = 8722174
257 + 8721917 = 8722174
401 + 8721773 = 8722174
557 + 8721617 = 8722174
641 + 8721533 = 8722174

Showing the first eight; more decompositions exist.
