Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731942, here are decompositions:

3 + 8731939 = 8731942
5 + 8731937 = 8731942
29 + 8731913 = 8731942
41 + 8731901 = 8731942
83 + 8731859 = 8731942
179 + 8731763 = 8731942
269 + 8731673 = 8731942
281 + 8731661 = 8731942

Showing the first eight; more decompositions exist.
