Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747542, here are decompositions:

3 + 8747539 = 8747542
29 + 8747513 = 8747542
53 + 8747489 = 8747542
59 + 8747483 = 8747542
71 + 8747471 = 8747542
101 + 8747441 = 8747542
269 + 8747273 = 8747542
281 + 8747261 = 8747542

Showing the first eight; more decompositions exist.
