Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702642, here are decompositions:

73 + 8702569 = 8702642
103 + 8702539 = 8702642
139 + 8702503 = 8702642
211 + 8702431 = 8702642
271 + 8702371 = 8702642
283 + 8702359 = 8702642
313 + 8702329 = 8702642
331 + 8702311 = 8702642

Showing the first eight; more decompositions exist.
