Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743838, here are decompositions:

31 + 8743807 = 8743838
67 + 8743771 = 8743838
127 + 8743711 = 8743838
157 + 8743681 = 8743838
199 + 8743639 = 8743838
241 + 8743597 = 8743838
277 + 8743561 = 8743838
307 + 8743531 = 8743838

Showing the first eight; more decompositions exist.
