Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72580, here are decompositions:

3 + 72577 = 72580
29 + 72551 = 72580
47 + 72533 = 72580
83 + 72497 = 72580
113 + 72467 = 72580
149 + 72431 = 72580
197 + 72383 = 72580
227 + 72353 = 72580

Showing the first eight; more decompositions exist.
