Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736142, here are decompositions:

3 + 8736139 = 8736142
53 + 8736089 = 8736142
83 + 8736059 = 8736142
101 + 8736041 = 8736142
251 + 8735891 = 8736142
263 + 8735879 = 8736142
281 + 8735861 = 8736142
293 + 8735849 = 8736142

Showing the first eight; more decompositions exist.
