Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30838, here are decompositions:

29 + 30809 = 30838
131 + 30707 = 30838
149 + 30689 = 30838
167 + 30671 = 30838
281 + 30557 = 30838
347 + 30491 = 30838
389 + 30449 = 30838
449 + 30389 = 30838

Showing the first eight; more decompositions exist.
