Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612440, here are decompositions:

3 + 8612437 = 8612440
17 + 8612423 = 8612440
29 + 8612411 = 8612440
41 + 8612399 = 8612440
197 + 8612243 = 8612440
383 + 8612057 = 8612440
401 + 8612039 = 8612440
449 + 8611991 = 8612440

Showing the first eight; more decompositions exist.
