Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17642, here are decompositions:

19 + 17623 = 17642
43 + 17599 = 17642
61 + 17581 = 17642
73 + 17569 = 17642
103 + 17539 = 17642
151 + 17491 = 17642
193 + 17449 = 17642
199 + 17443 = 17642

Showing the first eight; more decompositions exist.
