Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740238, here are decompositions:

19 + 8740219 = 8740238
109 + 8740129 = 8740238
127 + 8740111 = 8740238
151 + 8740087 = 8740238
271 + 8739967 = 8740238
277 + 8739961 = 8740238
337 + 8739901 = 8740238
499 + 8739739 = 8740238

Showing the first eight; more decompositions exist.
