Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720296, here are decompositions:

107 + 8720189 = 8720296
239 + 8720057 = 8720296
269 + 8720027 = 8720296
353 + 8719943 = 8720296
449 + 8719847 = 8720296
479 + 8719817 = 8720296
593 + 8719703 = 8720296
719 + 8719577 = 8720296

Showing the first eight; more decompositions exist.
