Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756238, here are decompositions:

5 + 8756233 = 8756238
17 + 8756221 = 8756238
37 + 8756201 = 8756238
79 + 8756159 = 8756238
89 + 8756149 = 8756238
109 + 8756129 = 8756238
131 + 8756107 = 8756238
137 + 8756101 = 8756238

Showing the first eight; more decompositions exist.
