Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142754, here are decompositions:

43 + 142711 = 142754
97 + 142657 = 142754
163 + 142591 = 142754
181 + 142573 = 142754
211 + 142543 = 142754
373 + 142381 = 142754
397 + 142357 = 142754
457 + 142297 = 142754

Showing the first eight; more decompositions exist.
