Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111672, here are decompositions:

5 + 111667 = 111672
13 + 111659 = 111672
19 + 111653 = 111672
31 + 111641 = 111672
61 + 111611 = 111672
73 + 111599 = 111672
79 + 111593 = 111672
139 + 111533 = 111672

Showing the first eight; more decompositions exist.
