Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142854, here are decompositions:

13 + 142841 = 142854
17 + 142837 = 142854
43 + 142811 = 142854
67 + 142787 = 142854
83 + 142771 = 142854
97 + 142757 = 142854
157 + 142697 = 142854
181 + 142673 = 142854

Showing the first eight; more decompositions exist.
