Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732186, here are decompositions:

139 + 8732047 = 8732186
157 + 8732029 = 8732186
163 + 8732023 = 8732186
193 + 8731993 = 8732186
313 + 8731873 = 8732186
367 + 8731819 = 8732186
409 + 8731777 = 8732186
487 + 8731699 = 8732186

Showing the first eight; more decompositions exist.
