Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739830, here are decompositions:

3 + 8739827 = 8739830
7 + 8739823 = 8739830
19 + 8739811 = 8739830
61 + 8739769 = 8739830
109 + 8739721 = 8739830
157 + 8739673 = 8739830
163 + 8739667 = 8739830
193 + 8739637 = 8739830

Showing the first eight; more decompositions exist.
