Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612040, here are decompositions:

7 + 8612033 = 8612040
29 + 8612011 = 8612040
53 + 8611987 = 8612040
71 + 8611969 = 8612040
79 + 8611961 = 8612040
137 + 8611903 = 8612040
149 + 8611891 = 8612040
167 + 8611873 = 8612040

Showing the first eight; more decompositions exist.
