Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702542, here are decompositions:

3 + 8702539 = 8702542
53 + 8702489 = 8702542
59 + 8702483 = 8702542
83 + 8702459 = 8702542
131 + 8702411 = 8702542
263 + 8702279 = 8702542
311 + 8702231 = 8702542
353 + 8702189 = 8702542

Showing the first eight; more decompositions exist.
