Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142446, here are decompositions:

13 + 142433 = 142446
19 + 142427 = 142446
43 + 142403 = 142446
89 + 142357 = 142446
127 + 142319 = 142446
149 + 142297 = 142446
223 + 142223 = 142446
229 + 142217 = 142446

Showing the first eight; more decompositions exist.
