Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27642, here are decompositions:

11 + 27631 = 27642
31 + 27611 = 27642
59 + 27583 = 27642
61 + 27581 = 27642
101 + 27541 = 27642
103 + 27539 = 27642
113 + 27529 = 27642
163 + 27479 = 27642

Showing the first eight; more decompositions exist.
