Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64142, here are decompositions:

19 + 64123 = 64142
61 + 64081 = 64142
79 + 64063 = 64142
109 + 64033 = 64142
193 + 63949 = 64142
229 + 63913 = 64142
241 + 63901 = 64142
349 + 63793 = 64142

Showing the first eight; more decompositions exist.
