Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155394, here are decompositions:

7 + 155387 = 155394
11 + 155383 = 155394
13 + 155381 = 155394
17 + 155377 = 155394
23 + 155371 = 155394
61 + 155333 = 155394
67 + 155327 = 155394
103 + 155291 = 155394

Showing the first eight; more decompositions exist.
