Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725002, here are decompositions:

19 + 8724983 = 8725002
53 + 8724949 = 8725002
59 + 8724943 = 8725002
73 + 8724929 = 8725002
131 + 8724871 = 8725002
199 + 8724803 = 8725002
263 + 8724739 = 8725002
281 + 8724721 = 8725002

Showing the first eight; more decompositions exist.
