Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749382, here are decompositions:

73 + 8749309 = 8749382
139 + 8749243 = 8749382
163 + 8749219 = 8749382
241 + 8749141 = 8749382
409 + 8748973 = 8749382
541 + 8748841 = 8749382
571 + 8748811 = 8749382
643 + 8748739 = 8749382

Showing the first eight; more decompositions exist.
