Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140428, here are decompositions:
- 5 + 140423 = 140428
- 11 + 140417 = 140428
- 17 + 140411 = 140428
- 47 + 140381 = 140428
- 89 + 140339 = 140428
- 107 + 140321 = 140428
- 131 + 140297 = 140428
- 179 + 140249 = 140428
Showing the first eight; more decompositions exist.
