Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612942, here are decompositions:

103 + 8612839 = 8612942
199 + 8612743 = 8612942
211 + 8612731 = 8612942
229 + 8612713 = 8612942
241 + 8612701 = 8612942
271 + 8612671 = 8612942
313 + 8612629 = 8612942
439 + 8612503 = 8612942

Showing the first eight; more decompositions exist.
