Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111640, here are decompositions:

3 + 111637 = 111640
17 + 111623 = 111640
29 + 111611 = 111640
41 + 111599 = 111640
47 + 111593 = 111640
59 + 111581 = 111640
101 + 111539 = 111640
107 + 111533 = 111640

Showing the first eight; more decompositions exist.
