Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142106, here are decompositions:

7 + 142099 = 142106
67 + 142039 = 142106
199 + 141907 = 142106
277 + 141829 = 142106
313 + 141793 = 142106
337 + 141769 = 142106
397 + 141709 = 142106
409 + 141697 = 142106

Showing the first eight; more decompositions exist.
