Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164564, here are decompositions:

61 + 164503 = 164564
151 + 164413 = 164564
193 + 164371 = 164564
223 + 164341 = 164564
313 + 164251 = 164564
331 + 164233 = 164564
373 + 164191 = 164564
541 + 164023 = 164564

Showing the first eight; more decompositions exist.
