Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40988, here are decompositions:
- 61 + 40927 = 40988
- 109 + 40879 = 40988
- 139 + 40849 = 40988
- 229 + 40759 = 40988
- 349 + 40639 = 40988
- 379 + 40609 = 40988
- 397 + 40591 = 40988
- 457 + 40531 = 40988
Showing the first eight; more decompositions exist.
