Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720492, here are decompositions:

3 + 8720489 = 8720492
13 + 8720479 = 8720492
61 + 8720431 = 8720492
103 + 8720389 = 8720492
181 + 8720311 = 8720492
211 + 8720281 = 8720492
331 + 8720161 = 8720492
373 + 8720119 = 8720492

Showing the first eight; more decompositions exist.
