Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742340, here are decompositions:

23 + 8742317 = 8742340
179 + 8742161 = 8742340
263 + 8742077 = 8742340
281 + 8742059 = 8742340
353 + 8741987 = 8742340
389 + 8741951 = 8742340
479 + 8741861 = 8742340
587 + 8741753 = 8742340

Showing the first eight; more decompositions exist.
