Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515188, here are decompositions:

101 + 515087 = 515188
239 + 514949 = 515188
347 + 514841 = 515188
419 + 514769 = 515188
431 + 514757 = 515188
449 + 514739 = 515188
617 + 514571 = 515188
659 + 514529 = 515188

Showing the first eight; more decompositions exist.
