Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164844, here are decompositions:

5 + 164839 = 164844
7 + 164837 = 164844
13 + 164831 = 164844
23 + 164821 = 164844
73 + 164771 = 164844
101 + 164743 = 164844
137 + 164707 = 164844
167 + 164677 = 164844

Showing the first eight; more decompositions exist.
