Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72590, here are decompositions:

13 + 72577 = 72590
31 + 72559 = 72590
43 + 72547 = 72590
97 + 72493 = 72590
109 + 72481 = 72590
211 + 72379 = 72590
223 + 72367 = 72590
277 + 72313 = 72590

Showing the first eight; more decompositions exist.
