Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42830, here are decompositions:

37 + 42793 = 42830
43 + 42787 = 42830
79 + 42751 = 42830
103 + 42727 = 42830
127 + 42703 = 42830
163 + 42667 = 42830
181 + 42649 = 42830
241 + 42589 = 42830

Showing the first eight; more decompositions exist.
