Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142860, here are decompositions:

19 + 142841 = 142860
23 + 142837 = 142860
61 + 142799 = 142860
71 + 142789 = 142860
73 + 142787 = 142860
89 + 142771 = 142860
101 + 142759 = 142860
103 + 142757 = 142860

Showing the first eight; more decompositions exist.
