Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720014, here are decompositions:

53 + 8719961 = 8720014
71 + 8719943 = 8720014
167 + 8719847 = 8720014
197 + 8719817 = 8720014
311 + 8719703 = 8720014
353 + 8719661 = 8720014
593 + 8719421 = 8720014
647 + 8719367 = 8720014

Showing the first eight; more decompositions exist.
