Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720204, here are decompositions:

13 + 8720191 = 8720204
43 + 8720161 = 8720204
67 + 8720137 = 8720204
331 + 8719873 = 8720204
373 + 8719831 = 8720204
433 + 8719771 = 8720204
457 + 8719747 = 8720204
523 + 8719681 = 8720204

Showing the first eight; more decompositions exist.
