Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538142, here are decompositions:

19 + 538123 = 538142
151 + 537991 = 538142
223 + 537919 = 538142
229 + 537913 = 538142
331 + 537811 = 538142
349 + 537793 = 538142
373 + 537769 = 538142
433 + 537709 = 538142

Showing the first eight; more decompositions exist.
