Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702408, here are decompositions:

37 + 8702371 = 8702408
67 + 8702341 = 8702408
79 + 8702329 = 8702408
97 + 8702311 = 8702408
157 + 8702251 = 8702408
229 + 8702179 = 8702408
271 + 8702137 = 8702408
277 + 8702131 = 8702408

Showing the first eight; more decompositions exist.
