Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71454, here are decompositions:
- 11 + 71443 = 71454
- 17 + 71437 = 71454
- 41 + 71413 = 71454
- 43 + 71411 = 71454
- 67 + 71387 = 71454
- 101 + 71353 = 71454
- 107 + 71347 = 71454
- 113 + 71341 = 71454
Showing the first eight; more decompositions exist.
