Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731394, here are decompositions:

13 + 8731381 = 8731394
31 + 8731363 = 8731394
73 + 8731321 = 8731394
163 + 8731231 = 8731394
181 + 8731213 = 8731394
193 + 8731201 = 8731394
241 + 8731153 = 8731394
283 + 8731111 = 8731394

Showing the first eight; more decompositions exist.
