Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30038, here are decompositions:

79 + 29959 = 30038
157 + 29881 = 30038
277 + 29761 = 30038
367 + 29671 = 30038
397 + 29641 = 30038
409 + 29629 = 30038
439 + 29599 = 30038
457 + 29581 = 30038

Showing the first eight; more decompositions exist.
