Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71450, here are decompositions:
- 7 + 71443 = 71450
- 13 + 71437 = 71450
- 31 + 71419 = 71450
- 37 + 71413 = 71450
- 61 + 71389 = 71450
- 97 + 71353 = 71450
- 103 + 71347 = 71450
- 109 + 71341 = 71450
Showing the first eight; more decompositions exist.
