Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700542, here are decompositions:

3 + 8700539 = 8700542
13 + 8700529 = 8700542
31 + 8700511 = 8700542
181 + 8700361 = 8700542
349 + 8700193 = 8700542
373 + 8700169 = 8700542
421 + 8700121 = 8700542
463 + 8700079 = 8700542

Showing the first eight; more decompositions exist.
