Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612420, here are decompositions:

7 + 8612413 = 8612420
73 + 8612347 = 8612420
109 + 8612311 = 8612420
127 + 8612293 = 8612420
199 + 8612221 = 8612420
211 + 8612209 = 8612420
331 + 8612089 = 8612420
409 + 8612011 = 8612420

Showing the first eight; more decompositions exist.
