Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725132, here are decompositions:

29 + 8725103 = 8725132
41 + 8725091 = 8725132
149 + 8724983 = 8725132
419 + 8724713 = 8725132
491 + 8724641 = 8725132
653 + 8724479 = 8725132
761 + 8724371 = 8725132
809 + 8724323 = 8725132

Showing the first eight; more decompositions exist.
