Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702442, here are decompositions:

11 + 8702431 = 8702442
31 + 8702411 = 8702442
71 + 8702371 = 8702442
83 + 8702359 = 8702442
101 + 8702341 = 8702442
109 + 8702333 = 8702442
113 + 8702329 = 8702442
131 + 8702311 = 8702442

Showing the first eight; more decompositions exist.
