Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743172, here are decompositions:

3 + 8743169 = 8743172
73 + 8743099 = 8743172
199 + 8742973 = 8743172
241 + 8742931 = 8743172
433 + 8742739 = 8743172
499 + 8742673 = 8743172
601 + 8742571 = 8743172
631 + 8742541 = 8743172

Showing the first eight; more decompositions exist.
