Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731186, here are decompositions:

47 + 8731139 = 8731186
83 + 8731103 = 8731186
89 + 8731097 = 8731186
239 + 8730947 = 8731186
257 + 8730929 = 8731186
293 + 8730893 = 8731186
383 + 8730803 = 8731186
389 + 8730797 = 8731186

Showing the first eight; more decompositions exist.
