Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71144, here are decompositions:

163 + 70981 = 71144
193 + 70951 = 71144
223 + 70921 = 71144
277 + 70867 = 71144
457 + 70687 = 71144
487 + 70657 = 71144
523 + 70621 = 71144
571 + 70573 = 71144

Showing the first eight; more decompositions exist.
