Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721362, here are decompositions:

3 + 8721359 = 8721362
103 + 8721259 = 8721362
109 + 8721253 = 8721362
241 + 8721121 = 8721362
283 + 8721079 = 8721362
313 + 8721049 = 8721362
409 + 8720953 = 8721362
421 + 8720941 = 8721362

Showing the first eight; more decompositions exist.
