Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71516, here are decompositions:
- 13 + 71503 = 71516
- 37 + 71479 = 71516
- 43 + 71473 = 71516
- 73 + 71443 = 71516
- 79 + 71437 = 71516
- 97 + 71419 = 71516
- 103 + 71413 = 71516
- 127 + 71389 = 71516
Showing the first eight; more decompositions exist.
