Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612156, here are decompositions:

37 + 8612119 = 8612156
67 + 8612089 = 8612156
97 + 8612059 = 8612156
277 + 8611879 = 8612156
283 + 8611873 = 8612156
307 + 8611849 = 8612156
337 + 8611819 = 8612156
367 + 8611789 = 8612156

Showing the first eight; more decompositions exist.
