Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702420, here are decompositions:

61 + 8702359 = 8702420
79 + 8702341 = 8702420
109 + 8702311 = 8702420
241 + 8702179 = 8702420
271 + 8702149 = 8702420
283 + 8702137 = 8702420
313 + 8702107 = 8702420
421 + 8701999 = 8702420

Showing the first eight; more decompositions exist.
