Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742252, here are decompositions:

59 + 8742193 = 8742252
83 + 8742169 = 8742252
131 + 8742121 = 8742252
149 + 8742103 = 8742252
193 + 8742059 = 8742252
241 + 8742011 = 8742252
263 + 8741989 = 8742252
269 + 8741983 = 8742252

Showing the first eight; more decompositions exist.
