Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702478, here are decompositions:

19 + 8702459 = 8702478
47 + 8702431 = 8702478
67 + 8702411 = 8702478
107 + 8702371 = 8702478
137 + 8702341 = 8702478
149 + 8702329 = 8702478
151 + 8702327 = 8702478
167 + 8702311 = 8702478

Showing the first eight; more decompositions exist.
