Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72832, here are decompositions:

113 + 72719 = 72832
131 + 72701 = 72832
281 + 72551 = 72832
401 + 72431 = 72832
449 + 72383 = 72832
479 + 72353 = 72832
491 + 72341 = 72832
563 + 72269 = 72832

Showing the first eight; more decompositions exist.
