Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112890, here are decompositions:

13 + 112877 = 112890
31 + 112859 = 112890
47 + 112843 = 112890
59 + 112831 = 112890
83 + 112807 = 112890
103 + 112787 = 112890
131 + 112759 = 112890
149 + 112741 = 112890

Showing the first eight; more decompositions exist.
