Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947278, here are decompositions:

107 + 947171 = 947278
149 + 947129 = 947278
251 + 947027 = 947278
281 + 946997 = 947278
317 + 946961 = 947278
347 + 946931 = 947278
359 + 946919 = 947278
401 + 946877 = 947278

Showing the first eight; more decompositions exist.
