Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612492, here are decompositions:

13 + 8612479 = 8612492
19 + 8612473 = 8612492
79 + 8612413 = 8612492
181 + 8612311 = 8612492
193 + 8612299 = 8612492
199 + 8612293 = 8612492
271 + 8612221 = 8612492
283 + 8612209 = 8612492

Showing the first eight; more decompositions exist.
