Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738904, here are decompositions:

23 + 8738881 = 8738904
61 + 8738843 = 8738904
67 + 8738837 = 8738904
103 + 8738801 = 8738904
137 + 8738767 = 8738904
191 + 8738713 = 8738904
193 + 8738711 = 8738904
197 + 8738707 = 8738904

Showing the first eight; more decompositions exist.
