Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164144, here are decompositions:

31 + 164113 = 164144
73 + 164071 = 164144
151 + 163993 = 164144
157 + 163987 = 164144
163 + 163981 = 164144
283 + 163861 = 164144
373 + 163771 = 164144
523 + 163621 = 164144

Showing the first eight; more decompositions exist.
