Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720002, here are decompositions:

3 + 8719999 = 8720002
41 + 8719961 = 8720002
59 + 8719943 = 8720002
461 + 8719541 = 8720002
653 + 8719349 = 8720002
701 + 8719301 = 8720002
839 + 8719163 = 8720002
953 + 8719049 = 8720002

Showing the first eight; more decompositions exist.
