Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523142, here are decompositions:

13 + 523129 = 523142
181 + 522961 = 523142
199 + 522943 = 523142
223 + 522919 = 523142
271 + 522871 = 523142
313 + 522829 = 523142
331 + 522811 = 523142
379 + 522763 = 523142

Showing the first eight; more decompositions exist.
