Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72650, here are decompositions:
- 3 + 72647 = 72650
- 7 + 72643 = 72650
- 37 + 72613 = 72650
- 73 + 72577 = 72650
- 103 + 72547 = 72650
- 157 + 72493 = 72650
- 181 + 72469 = 72650
- 229 + 72421 = 72650
Showing the first eight; more decompositions exist.
