Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740278, here are decompositions:

5 + 8740273 = 8740278
59 + 8740219 = 8740278
109 + 8740169 = 8740278
139 + 8740139 = 8740278
149 + 8740129 = 8740278
167 + 8740111 = 8740278
181 + 8740097 = 8740278
191 + 8740087 = 8740278

Showing the first eight; more decompositions exist.
