Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127842, here are decompositions:

5 + 127837 = 127842
23 + 127819 = 127842
61 + 127781 = 127842
79 + 127763 = 127842
103 + 127739 = 127842
109 + 127733 = 127842
131 + 127711 = 127842
139 + 127703 = 127842

Showing the first eight; more decompositions exist.
