Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164738, here are decompositions:

31 + 164707 = 164738
37 + 164701 = 164738
61 + 164677 = 164738
139 + 164599 = 164738
151 + 164587 = 164738
157 + 164581 = 164738
307 + 164431 = 164738
367 + 164371 = 164738

Showing the first eight; more decompositions exist.
