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.
