Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731236, here are decompositions:

5 + 8731231 = 8731236
23 + 8731213 = 8731236
83 + 8731153 = 8731236
97 + 8731139 = 8731236
127 + 8731109 = 8731236
139 + 8731097 = 8731236
167 + 8731069 = 8731236
197 + 8731039 = 8731236

Showing the first eight; more decompositions exist.
