Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731946, here are decompositions:

7 + 8731939 = 8731946
73 + 8731873 = 8731946
79 + 8731867 = 8731946
127 + 8731819 = 8731946
163 + 8731783 = 8731946
337 + 8731609 = 8731946
367 + 8731579 = 8731946
499 + 8731447 = 8731946

Showing the first eight; more decompositions exist.
