Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702438, here are decompositions:

7 + 8702431 = 8702438
67 + 8702371 = 8702438
79 + 8702359 = 8702438
97 + 8702341 = 8702438
109 + 8702329 = 8702438
127 + 8702311 = 8702438
307 + 8702131 = 8702438
331 + 8702107 = 8702438

Showing the first eight; more decompositions exist.
