Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725156, here are decompositions:

3 + 8725153 = 8725156
17 + 8725139 = 8725156
23 + 8725133 = 8725156
53 + 8725103 = 8725156
173 + 8724983 = 8725156
227 + 8724929 = 8725156
353 + 8724803 = 8725156
443 + 8724713 = 8725156

Showing the first eight; more decompositions exist.
