Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725142, here are decompositions:

3 + 8725139 = 8725142
31 + 8725111 = 8725142
43 + 8725099 = 8725142
103 + 8725039 = 8725142
193 + 8724949 = 8725142
199 + 8724943 = 8725142
271 + 8724871 = 8725142
421 + 8724721 = 8725142

Showing the first eight; more decompositions exist.
