Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189142, here are decompositions:

3 + 189139 = 189142
101 + 189041 = 189142
131 + 189011 = 189142
251 + 188891 = 189142
281 + 188861 = 189142
311 + 188831 = 189142
389 + 188753 = 189142
431 + 188711 = 189142

Showing the first eight; more decompositions exist.
