Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745742, here are decompositions:

59 + 8745683 = 8745742
191 + 8745551 = 8745742
293 + 8745449 = 8745742
389 + 8745353 = 8745742
431 + 8745311 = 8745742
443 + 8745299 = 8745742
503 + 8745239 = 8745742
641 + 8745101 = 8745742

Showing the first eight; more decompositions exist.
