Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72908, here are decompositions:
- 7 + 72901 = 72908
- 19 + 72889 = 72908
- 37 + 72871 = 72908
- 181 + 72727 = 72908
- 229 + 72679 = 72908
- 331 + 72577 = 72908
- 349 + 72559 = 72908
- 439 + 72469 = 72908
Showing the first eight; more decompositions exist.
