Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725830, here are decompositions:

7 + 8725823 = 8725830
13 + 8725817 = 8725830
17 + 8725813 = 8725830
31 + 8725799 = 8725830
73 + 8725757 = 8725830
97 + 8725733 = 8725830
131 + 8725699 = 8725830
149 + 8725681 = 8725830

Showing the first eight; more decompositions exist.
