Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740178, here are decompositions:

61 + 8740117 = 8740178
67 + 8740111 = 8740178
211 + 8739967 = 8740178
241 + 8739937 = 8740178
277 + 8739901 = 8740178
367 + 8739811 = 8740178
409 + 8739769 = 8740178
439 + 8739739 = 8740178

Showing the first eight; more decompositions exist.
