Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142350, here are decompositions:

23 + 142327 = 142350
31 + 142319 = 142350
53 + 142297 = 142350
79 + 142271 = 142350
113 + 142237 = 142350
127 + 142223 = 142350
139 + 142211 = 142350
157 + 142193 = 142350

Showing the first eight; more decompositions exist.
