Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152442, here are decompositions:

13 + 152429 = 152442
19 + 152423 = 152442
23 + 152419 = 152442
53 + 152389 = 152442
61 + 152381 = 152442
79 + 152363 = 152442
131 + 152311 = 152442
149 + 152293 = 152442

Showing the first eight; more decompositions exist.
