Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190142, here are decompositions:

13 + 190129 = 190142
79 + 190063 = 190142
181 + 189961 = 190142
193 + 189949 = 190142
229 + 189913 = 190142
241 + 189901 = 190142
283 + 189859 = 190142
409 + 189733 = 190142

Showing the first eight; more decompositions exist.
