Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742460, here are decompositions:

11 + 8742449 = 8742460
59 + 8742401 = 8742460
101 + 8742359 = 8742460
107 + 8742353 = 8742460
113 + 8742347 = 8742460
197 + 8742263 = 8742460
263 + 8742197 = 8742460
383 + 8742077 = 8742460

Showing the first eight; more decompositions exist.
