Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612400, here are decompositions:

53 + 8612347 = 8612400
89 + 8612311 = 8612400
101 + 8612299 = 8612400
107 + 8612293 = 8612400
157 + 8612243 = 8612400
179 + 8612221 = 8612400
191 + 8612209 = 8612400
233 + 8612167 = 8612400

Showing the first eight; more decompositions exist.
