Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42672, here are decompositions:

5 + 42667 = 42672
23 + 42649 = 42672
29 + 42643 = 42672
31 + 42641 = 42672
61 + 42611 = 42672
83 + 42589 = 42672
101 + 42571 = 42672
103 + 42569 = 42672

Showing the first eight; more decompositions exist.
