Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720494, here are decompositions:

5 + 8720489 = 8720494
11 + 8720483 = 8720494
17 + 8720477 = 8720494
23 + 8720471 = 8720494
47 + 8720447 = 8720494
173 + 8720321 = 8720494
317 + 8720177 = 8720494
383 + 8720111 = 8720494

Showing the first eight; more decompositions exist.
