Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743738, here are decompositions:

5 + 8743733 = 8743738
149 + 8743589 = 8743738
167 + 8743571 = 8743738
191 + 8743547 = 8743738
239 + 8743499 = 8743738
317 + 8743421 = 8743738
359 + 8743379 = 8743738
389 + 8743349 = 8743738

Showing the first eight; more decompositions exist.
