Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701890, here are decompositions:

7 + 8701883 = 8701890
13 + 8701877 = 8701890
17 + 8701873 = 8701890
19 + 8701871 = 8701890
37 + 8701853 = 8701890
79 + 8701811 = 8701890
101 + 8701789 = 8701890
149 + 8701741 = 8701890

Showing the first eight; more decompositions exist.
