Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713290, here are decompositions:

29 + 8713261 = 8713290
41 + 8713249 = 8713290
73 + 8713217 = 8713290
97 + 8713193 = 8713290
109 + 8713181 = 8713290
149 + 8713141 = 8713290
163 + 8713127 = 8713290
167 + 8713123 = 8713290

Showing the first eight; more decompositions exist.
