Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611542, here are decompositions:

11 + 8611531 = 8611542
13 + 8611529 = 8611542
19 + 8611523 = 8611542
41 + 8611501 = 8611542
101 + 8611441 = 8611542
103 + 8611439 = 8611542
109 + 8611433 = 8611542
131 + 8611411 = 8611542

Showing the first eight; more decompositions exist.
