Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731974, here are decompositions:

23 + 8731951 = 8731974
37 + 8731937 = 8731974
61 + 8731913 = 8731974
67 + 8731907 = 8731974
73 + 8731901 = 8731974
101 + 8731873 = 8731974
107 + 8731867 = 8731974
113 + 8731861 = 8731974

Showing the first eight; more decompositions exist.
