Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720532, here are decompositions:

19 + 8720513 = 8720532
43 + 8720489 = 8720532
53 + 8720479 = 8720532
61 + 8720471 = 8720532
101 + 8720431 = 8720532
103 + 8720429 = 8720532
193 + 8720339 = 8720532
211 + 8720321 = 8720532

Showing the first eight; more decompositions exist.
