Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22512, here are decompositions:

11 + 22501 = 22512
29 + 22483 = 22512
31 + 22481 = 22512
43 + 22469 = 22512
59 + 22453 = 22512
71 + 22441 = 22512
79 + 22433 = 22512
103 + 22409 = 22512

Showing the first eight; more decompositions exist.
