Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64838, here are decompositions:

211 + 64627 = 64838
229 + 64609 = 64838
271 + 64567 = 64838
349 + 64489 = 64838
439 + 64399 = 64838
457 + 64381 = 64838
601 + 64237 = 64838
607 + 64231 = 64838

Showing the first eight; more decompositions exist.
