Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702480, here are decompositions:

109 + 8702371 = 8702480
139 + 8702341 = 8702480
151 + 8702329 = 8702480
229 + 8702251 = 8702480
307 + 8702173 = 8702480
331 + 8702149 = 8702480
349 + 8702131 = 8702480
373 + 8702107 = 8702480

Showing the first eight; more decompositions exist.
