Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101072, here are decompositions:

73 + 100999 = 101072
271 + 100801 = 101072
331 + 100741 = 101072
373 + 100699 = 101072
379 + 100693 = 101072
463 + 100609 = 101072
523 + 100549 = 101072
571 + 100501 = 101072

Showing the first eight; more decompositions exist.
