Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749208, here are decompositions:

67 + 8749141 = 8749208
229 + 8748979 = 8749208
331 + 8748877 = 8749208
367 + 8748841 = 8749208
397 + 8748811 = 8749208
421 + 8748787 = 8749208
499 + 8748709 = 8749208
607 + 8748601 = 8749208

Showing the first eight; more decompositions exist.
