Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726402, here are decompositions:

19 + 8726383 = 8726402
43 + 8726359 = 8726402
73 + 8726329 = 8726402
79 + 8726323 = 8726402
163 + 8726239 = 8726402
193 + 8726209 = 8726402
199 + 8726203 = 8726402
439 + 8725963 = 8726402

Showing the first eight; more decompositions exist.
