Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721296, here are decompositions:

37 + 8721259 = 8721296
43 + 8721253 = 8721296
139 + 8721157 = 8721296
349 + 8720947 = 8721296
457 + 8720839 = 8721296
487 + 8720809 = 8721296
499 + 8720797 = 8721296
523 + 8720773 = 8721296

Showing the first eight; more decompositions exist.
