Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725100, here are decompositions:

61 + 8725039 = 8725100
79 + 8725021 = 8725100
151 + 8724949 = 8725100
157 + 8724943 = 8725100
229 + 8724871 = 8725100
313 + 8724787 = 8725100
379 + 8724721 = 8725100
457 + 8724643 = 8725100

Showing the first eight; more decompositions exist.
