Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111542, here are decompositions:

3 + 111539 = 111542
103 + 111439 = 111542
241 + 111301 = 111542
271 + 111271 = 111542
313 + 111229 = 111542
331 + 111211 = 111542
421 + 111121 = 111542
433 + 111109 = 111542

Showing the first eight; more decompositions exist.
