Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720410, here are decompositions:

3 + 8720407 = 8720410
71 + 8720339 = 8720410
89 + 8720321 = 8720410
233 + 8720177 = 8720410
239 + 8720171 = 8720410
353 + 8720057 = 8720410
383 + 8720027 = 8720410
449 + 8719961 = 8720410

Showing the first eight; more decompositions exist.
