Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142512, here are decompositions:

11 + 142501 = 142512
43 + 142469 = 142512
59 + 142453 = 142512
79 + 142433 = 142512
109 + 142403 = 142512
131 + 142381 = 142512
193 + 142319 = 142512
241 + 142271 = 142512

Showing the first eight; more decompositions exist.
