Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702378, here are decompositions:

7 + 8702371 = 8702378
19 + 8702359 = 8702378
37 + 8702341 = 8702378
67 + 8702311 = 8702378
127 + 8702251 = 8702378
199 + 8702179 = 8702378
229 + 8702149 = 8702378
241 + 8702137 = 8702378

Showing the first eight; more decompositions exist.
