Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72606, here are decompositions:

29 + 72577 = 72606
47 + 72559 = 72606
59 + 72547 = 72606
73 + 72533 = 72606
103 + 72503 = 72606
109 + 72497 = 72606
113 + 72493 = 72606
137 + 72469 = 72606

Showing the first eight; more decompositions exist.
