Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749244, here are decompositions:

37 + 8749207 = 8749244
103 + 8749141 = 8749244
157 + 8749087 = 8749244
271 + 8748973 = 8749244
367 + 8748877 = 8749244
397 + 8748847 = 8749244
433 + 8748811 = 8749244
457 + 8748787 = 8749244

Showing the first eight; more decompositions exist.
