Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72782, here are decompositions:

19 + 72763 = 72782
43 + 72739 = 72782
103 + 72679 = 72782
109 + 72673 = 72782
139 + 72643 = 72782
223 + 72559 = 72782
313 + 72469 = 72782
571 + 72211 = 72782

Showing the first eight; more decompositions exist.
