Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732018, here are decompositions:

37 + 8731981 = 8732018
67 + 8731951 = 8732018
79 + 8731939 = 8732018
151 + 8731867 = 8732018
157 + 8731861 = 8732018
199 + 8731819 = 8732018
241 + 8731777 = 8732018
307 + 8731711 = 8732018

Showing the first eight; more decompositions exist.
