Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731844, here are decompositions:

13 + 8731831 = 8731844
61 + 8731783 = 8731844
67 + 8731777 = 8731844
157 + 8731687 = 8731844
313 + 8731531 = 8731844
367 + 8731477 = 8731844
397 + 8731447 = 8731844
463 + 8731381 = 8731844

Showing the first eight; more decompositions exist.
