Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112830, here are decompositions:

23 + 112807 = 112830
31 + 112799 = 112830
43 + 112787 = 112830
59 + 112771 = 112830
71 + 112759 = 112830
73 + 112757 = 112830
89 + 112741 = 112830
139 + 112691 = 112830

Showing the first eight; more decompositions exist.
