Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725162, here are decompositions:

3 + 8725159 = 8725162
23 + 8725139 = 8725162
29 + 8725133 = 8725162
59 + 8725103 = 8725162
71 + 8725091 = 8725162
179 + 8724983 = 8725162
233 + 8724929 = 8725162
359 + 8724803 = 8725162

Showing the first eight; more decompositions exist.
