Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702418, here are decompositions:

7 + 8702411 = 8702418
31 + 8702387 = 8702418
47 + 8702371 = 8702418
59 + 8702359 = 8702418
89 + 8702329 = 8702418
107 + 8702311 = 8702418
139 + 8702279 = 8702418
167 + 8702251 = 8702418

Showing the first eight; more decompositions exist.
