Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111812, here are decompositions:

13 + 111799 = 111812
31 + 111781 = 111812
61 + 111751 = 111812
79 + 111733 = 111812
373 + 111439 = 111812
439 + 111373 = 111812
541 + 111271 = 111812
601 + 111211 = 111812

Showing the first eight; more decompositions exist.
