Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742974, here are decompositions:

43 + 8742931 = 8742974
127 + 8742847 = 8742974
157 + 8742817 = 8742974
337 + 8742637 = 8742974
397 + 8742577 = 8742974
433 + 8742541 = 8742974
463 + 8742511 = 8742974
607 + 8742367 = 8742974

Showing the first eight; more decompositions exist.
