Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88440, here are decompositions:
- 13 + 88427 = 88440
- 17 + 88423 = 88440
- 29 + 88411 = 88440
- 43 + 88397 = 88440
- 61 + 88379 = 88440
- 101 + 88339 = 88440
- 103 + 88337 = 88440
- 113 + 88327 = 88440
Showing the first eight; more decompositions exist.
