Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105642, here are decompositions:

23 + 105619 = 105642
29 + 105613 = 105642
41 + 105601 = 105642
79 + 105563 = 105642
101 + 105541 = 105642
109 + 105533 = 105642
113 + 105529 = 105642
139 + 105503 = 105642

Showing the first eight; more decompositions exist.
