Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152678, here are decompositions:

7 + 152671 = 152678
37 + 152641 = 152678
61 + 152617 = 152678
79 + 152599 = 152678
139 + 152539 = 152678
271 + 152407 = 152678
367 + 152311 = 152678
439 + 152239 = 152678

Showing the first eight; more decompositions exist.
