Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621202, here are decompositions:

13 + 8621189 = 8621202
19 + 8621183 = 8621202
59 + 8621143 = 8621202
101 + 8621101 = 8621202
113 + 8621089 = 8621202
151 + 8621051 = 8621202
193 + 8621009 = 8621202
229 + 8620973 = 8621202

Showing the first eight; more decompositions exist.
