Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71648, here are decompositions:
- 79 + 71569 = 71648
- 97 + 71551 = 71648
- 211 + 71437 = 71648
- 229 + 71419 = 71648
- 307 + 71341 = 71648
- 331 + 71317 = 71648
- 439 + 71209 = 71648
- 457 + 71191 = 71648
Showing the first eight; more decompositions exist.
