Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183142, here are decompositions:

23 + 183119 = 183142
53 + 183089 = 183142
83 + 183059 = 183142
101 + 183041 = 183142
173 + 182969 = 183142
353 + 182789 = 183142
431 + 182711 = 183142
461 + 182681 = 183142

Showing the first eight; more decompositions exist.
