Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702472, here are decompositions:

13 + 8702459 = 8702472
41 + 8702431 = 8702472
61 + 8702411 = 8702472
101 + 8702371 = 8702472
113 + 8702359 = 8702472
131 + 8702341 = 8702472
139 + 8702333 = 8702472
193 + 8702279 = 8702472

Showing the first eight; more decompositions exist.
