Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610440, here are decompositions:

31 + 8610409 = 8610440
37 + 8610403 = 8610440
61 + 8610379 = 8610440
67 + 8610373 = 8610440
73 + 8610367 = 8610440
109 + 8610331 = 8610440
193 + 8610247 = 8610440
211 + 8610229 = 8610440

Showing the first eight; more decompositions exist.
