Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731958, here are decompositions:

7 + 8731951 = 8731958
19 + 8731939 = 8731958
97 + 8731861 = 8731958
127 + 8731831 = 8731958
139 + 8731819 = 8731958
181 + 8731777 = 8731958
271 + 8731687 = 8731958
331 + 8731627 = 8731958

Showing the first eight; more decompositions exist.
