Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77438, here are decompositions:

7 + 77431 = 77438
19 + 77419 = 77438
61 + 77377 = 77438
79 + 77359 = 77438
199 + 77239 = 77438
271 + 77167 = 77438
337 + 77101 = 77438
397 + 77041 = 77438

Showing the first eight; more decompositions exist.
