Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105654, here are decompositions:

5 + 105649 = 105654
41 + 105613 = 105654
47 + 105607 = 105654
53 + 105601 = 105654
97 + 105557 = 105654
113 + 105541 = 105654
127 + 105527 = 105654
137 + 105517 = 105654

Showing the first eight; more decompositions exist.
