Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164444, here are decompositions:

13 + 164431 = 164444
31 + 164413 = 164444
67 + 164377 = 164444
73 + 164371 = 164444
103 + 164341 = 164444
193 + 164251 = 164444
211 + 164233 = 164444
271 + 164173 = 164444

Showing the first eight; more decompositions exist.
