Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740040, here are decompositions:

3 + 8740037 = 8740040
37 + 8740003 = 8740040
73 + 8739967 = 8740040
79 + 8739961 = 8740040
103 + 8739937 = 8740040
139 + 8739901 = 8740040
157 + 8739883 = 8740040
163 + 8739877 = 8740040

Showing the first eight; more decompositions exist.
