Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720044, here are decompositions:

17 + 8720027 = 8720044
83 + 8719961 = 8720044
101 + 8719943 = 8720044
197 + 8719847 = 8720044
227 + 8719817 = 8720044
383 + 8719661 = 8720044
467 + 8719577 = 8720044
503 + 8719541 = 8720044

Showing the first eight; more decompositions exist.
