Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738488, here are decompositions:

41 + 8738447 = 8738488
89 + 8738399 = 8738488
137 + 8738351 = 8738488
149 + 8738339 = 8738488
257 + 8738231 = 8738488
359 + 8738129 = 8738488
401 + 8738087 = 8738488
509 + 8737979 = 8738488

Showing the first eight; more decompositions exist.
