Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725412, here are decompositions:

13 + 8725399 = 8725412
193 + 8725219 = 8725412
229 + 8725183 = 8725412
271 + 8725141 = 8725412
313 + 8725099 = 8725412
373 + 8725039 = 8725412
463 + 8724949 = 8725412
541 + 8724871 = 8725412

Showing the first eight; more decompositions exist.
