Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742418, here are decompositions:

17 + 8742401 = 8742418
59 + 8742359 = 8742418
71 + 8742347 = 8742418
101 + 8742317 = 8742418
257 + 8742161 = 8742418
359 + 8742059 = 8742418
431 + 8741987 = 8742418
467 + 8741951 = 8742418

Showing the first eight; more decompositions exist.
