Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702222, here are decompositions:

43 + 8702179 = 8702222
73 + 8702149 = 8702222
223 + 8701999 = 8702222
271 + 8701951 = 8702222
349 + 8701873 = 8702222
409 + 8701813 = 8702222
433 + 8701789 = 8702222
499 + 8701723 = 8702222

Showing the first eight; more decompositions exist.
