Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612258, here are decompositions:

37 + 8612221 = 8612258
139 + 8612119 = 8612258
199 + 8612059 = 8612258
271 + 8611987 = 8612258
367 + 8611891 = 8612258
379 + 8611879 = 8612258
409 + 8611849 = 8612258
439 + 8611819 = 8612258

Showing the first eight; more decompositions exist.
