Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720602, here are decompositions:

5 + 8720597 = 8720602
71 + 8720531 = 8720602
89 + 8720513 = 8720602
113 + 8720489 = 8720602
131 + 8720471 = 8720602
173 + 8720429 = 8720602
263 + 8720339 = 8720602
281 + 8720321 = 8720602

Showing the first eight; more decompositions exist.
