Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72620, here are decompositions:

3 + 72617 = 72620
7 + 72613 = 72620
43 + 72577 = 72620
61 + 72559 = 72620
73 + 72547 = 72620
127 + 72493 = 72620
139 + 72481 = 72620
151 + 72469 = 72620

Showing the first eight; more decompositions exist.
