Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142748, here are decompositions:

37 + 142711 = 142748
139 + 142609 = 142748
157 + 142591 = 142748
181 + 142567 = 142748
211 + 142537 = 142748
367 + 142381 = 142748
379 + 142369 = 142748
421 + 142327 = 142748

Showing the first eight; more decompositions exist.
