Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741530, here are decompositions:

59 + 8741471 = 8741530
71 + 8741459 = 8741530
137 + 8741393 = 8741530
167 + 8741363 = 8741530
227 + 8741303 = 8741530
251 + 8741279 = 8741530
383 + 8741147 = 8741530
389 + 8741141 = 8741530

Showing the first eight; more decompositions exist.
