Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42818, here are decompositions:

31 + 42787 = 42818
67 + 42751 = 42818
109 + 42709 = 42818
151 + 42667 = 42818
229 + 42589 = 42818
241 + 42577 = 42818
331 + 42487 = 42818
367 + 42451 = 42818

Showing the first eight; more decompositions exist.
