Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111644, here are decompositions:

3 + 111641 = 111644
7 + 111637 = 111644
67 + 111577 = 111644
151 + 111493 = 111644
157 + 111487 = 111644
271 + 111373 = 111644
307 + 111337 = 111644
373 + 111271 = 111644

Showing the first eight; more decompositions exist.
