Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761542, here are decompositions:

5 + 8761537 = 8761542
11 + 8761531 = 8761542
73 + 8761469 = 8761542
79 + 8761463 = 8761542
89 + 8761453 = 8761542
103 + 8761439 = 8761542
109 + 8761433 = 8761542
113 + 8761429 = 8761542

Showing the first eight; more decompositions exist.
