Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749136, here are decompositions:

3 + 8749133 = 8749136
157 + 8748979 = 8749136
163 + 8748973 = 8749136
283 + 8748853 = 8749136
349 + 8748787 = 8749136
397 + 8748739 = 8749136
463 + 8748673 = 8749136
547 + 8748589 = 8749136

Showing the first eight; more decompositions exist.
