Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713242, here are decompositions:

29 + 8713213 = 8713242
61 + 8713181 = 8713242
101 + 8713141 = 8713242
173 + 8713069 = 8713242
191 + 8713051 = 8713242
199 + 8713043 = 8713242
229 + 8713013 = 8713242
233 + 8713009 = 8713242

Showing the first eight; more decompositions exist.
