Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13670, here are decompositions:

37 + 13633 = 13670
43 + 13627 = 13670
73 + 13597 = 13670
79 + 13591 = 13670
103 + 13567 = 13670
157 + 13513 = 13670
193 + 13477 = 13670
229 + 13441 = 13670

Showing the first eight; more decompositions exist.
