Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725446, here are decompositions:

17 + 8725429 = 8725446
47 + 8725399 = 8725446
83 + 8725363 = 8725446
89 + 8725357 = 8725446
127 + 8725319 = 8725446
139 + 8725307 = 8725446
167 + 8725279 = 8725446
193 + 8725253 = 8725446

Showing the first eight; more decompositions exist.
