Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725190, here are decompositions:

7 + 8725183 = 8725190
13 + 8725177 = 8725190
31 + 8725159 = 8725190
37 + 8725153 = 8725190
43 + 8725147 = 8725190
79 + 8725111 = 8725190
139 + 8725051 = 8725190
151 + 8725039 = 8725190

Showing the first eight; more decompositions exist.
