Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701906, here are decompositions:

23 + 8701883 = 8701906
29 + 8701877 = 8701906
53 + 8701853 = 8701906
149 + 8701757 = 8701906
197 + 8701709 = 8701906
263 + 8701643 = 8701906
347 + 8701559 = 8701906
449 + 8701457 = 8701906

Showing the first eight; more decompositions exist.
