Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71510, here are decompositions:
- 7 + 71503 = 71510
- 31 + 71479 = 71510
- 37 + 71473 = 71510
- 67 + 71443 = 71510
- 73 + 71437 = 71510
- 97 + 71413 = 71510
- 151 + 71359 = 71510
- 157 + 71353 = 71510
Showing the first eight; more decompositions exist.
