Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702424, here are decompositions:

13 + 8702411 = 8702424
37 + 8702387 = 8702424
53 + 8702371 = 8702424
83 + 8702341 = 8702424
97 + 8702327 = 8702424
113 + 8702311 = 8702424
173 + 8702251 = 8702424
193 + 8702231 = 8702424

Showing the first eight; more decompositions exist.
