Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611402, here are decompositions:

3 + 8611399 = 8611402
53 + 8611349 = 8611402
71 + 8611331 = 8611402
101 + 8611301 = 8611402
251 + 8611151 = 8611402
263 + 8611139 = 8611402
269 + 8611133 = 8611402
509 + 8610893 = 8611402

Showing the first eight; more decompositions exist.
