Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111842, here are decompositions:

13 + 111829 = 111842
43 + 111799 = 111842
61 + 111781 = 111842
109 + 111733 = 111842
349 + 111493 = 111842
433 + 111409 = 111842
541 + 111301 = 111842
571 + 111271 = 111842

Showing the first eight; more decompositions exist.
