Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725904, here are decompositions:

73 + 8725831 = 8725904
223 + 8725681 = 8725904
277 + 8725627 = 8725904
283 + 8725621 = 8725904
337 + 8725567 = 8725904
373 + 8725531 = 8725904
541 + 8725363 = 8725904
547 + 8725357 = 8725904

Showing the first eight; more decompositions exist.
