Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622658, here are decompositions:

47 + 8622611 = 8622658
137 + 8622521 = 8622658
167 + 8622491 = 8622658
197 + 8622461 = 8622658
449 + 8622209 = 8622658
467 + 8622191 = 8622658
521 + 8622137 = 8622658
587 + 8622071 = 8622658

Showing the first eight; more decompositions exist.
