Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753420, here are decompositions:

19 + 8753401 = 8753420
61 + 8753359 = 8753420
127 + 8753293 = 8753420
163 + 8753257 = 8753420
223 + 8753197 = 8753420
271 + 8753149 = 8753420
331 + 8753089 = 8753420
337 + 8753083 = 8753420

Showing the first eight; more decompositions exist.
