Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65144, here are decompositions:

3 + 65141 = 65144
43 + 65101 = 65144
73 + 65071 = 65144
193 + 64951 = 65144
223 + 64921 = 65144
397 + 64747 = 65144
523 + 64621 = 65144
577 + 64567 = 65144

Showing the first eight; more decompositions exist.
