Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620124, here are decompositions:

3 + 8620121 = 8620124
13 + 8620111 = 8620124
61 + 8620063 = 8620124
127 + 8619997 = 8620124
181 + 8619943 = 8620124
241 + 8619883 = 8620124
307 + 8619817 = 8620124
313 + 8619811 = 8620124

Showing the first eight; more decompositions exist.
