Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718272, here are decompositions:

109 + 8718163 = 8718272
163 + 8718109 = 8718272
181 + 8718091 = 8718272
229 + 8718043 = 8718272
313 + 8717959 = 8718272
463 + 8717809 = 8718272
499 + 8717773 = 8718272
523 + 8717749 = 8718272

Showing the first eight; more decompositions exist.
