Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611390, here are decompositions:

41 + 8611349 = 8611390
59 + 8611331 = 8611390
83 + 8611307 = 8611390
89 + 8611301 = 8611390
107 + 8611283 = 8611390
239 + 8611151 = 8611390
251 + 8611139 = 8611390
257 + 8611133 = 8611390

Showing the first eight; more decompositions exist.
