Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620154, here are decompositions:

3 + 8620151 = 8620154
13 + 8620141 = 8620154
43 + 8620111 = 8620154
157 + 8619997 = 8620154
211 + 8619943 = 8620154
271 + 8619883 = 8620154
337 + 8619817 = 8620154
643 + 8619511 = 8620154

Showing the first eight; more decompositions exist.
