Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42636, here are decompositions:

47 + 42589 = 42636
59 + 42577 = 42636
67 + 42569 = 42636
79 + 42557 = 42636
103 + 42533 = 42636
127 + 42509 = 42636
137 + 42499 = 42636
149 + 42487 = 42636

Showing the first eight; more decompositions exist.
