Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142670, here are decompositions:

13 + 142657 = 142670
61 + 142609 = 142670
79 + 142591 = 142670
97 + 142573 = 142670
103 + 142567 = 142670
127 + 142543 = 142670
313 + 142357 = 142670
373 + 142297 = 142670

Showing the first eight; more decompositions exist.
