Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111820, here are decompositions:

29 + 111791 = 111820
41 + 111779 = 111820
47 + 111773 = 111820
53 + 111767 = 111820
89 + 111731 = 111820
167 + 111653 = 111820
179 + 111641 = 111820
197 + 111623 = 111820

Showing the first eight; more decompositions exist.
