Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73870, here are decompositions:

3 + 73867 = 73870
11 + 73859 = 73870
23 + 73847 = 73870
47 + 73823 = 73870
113 + 73757 = 73870
149 + 73721 = 73870
191 + 73679 = 73870
197 + 73673 = 73870

Showing the first eight; more decompositions exist.
