Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725144, here are decompositions:

3 + 8725141 = 8725144
5 + 8725139 = 8725144
11 + 8725133 = 8725144
41 + 8725103 = 8725144
53 + 8725091 = 8725144
107 + 8725037 = 8725144
317 + 8724827 = 8725144
431 + 8724713 = 8725144

Showing the first eight; more decompositions exist.
