Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136842, here are decompositions:

29 + 136813 = 136842
31 + 136811 = 136842
73 + 136769 = 136842
89 + 136753 = 136842
103 + 136739 = 136842
109 + 136733 = 136842
131 + 136711 = 136842
149 + 136693 = 136842

Showing the first eight; more decompositions exist.
