Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736172, here are decompositions:

83 + 8736089 = 8736172
113 + 8736059 = 8736172
131 + 8736041 = 8736172
239 + 8735933 = 8736172
281 + 8735891 = 8736172
293 + 8735879 = 8736172
311 + 8735861 = 8736172
359 + 8735813 = 8736172

Showing the first eight; more decompositions exist.
