Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725192, here are decompositions:

53 + 8725139 = 8725192
59 + 8725133 = 8725192
89 + 8725103 = 8725192
101 + 8725091 = 8725192
263 + 8724929 = 8725192
389 + 8724803 = 8725192
479 + 8724713 = 8725192
821 + 8724371 = 8725192

Showing the first eight; more decompositions exist.
