Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71524, here are decompositions:
- 41 + 71483 = 71524
- 53 + 71471 = 71524
- 71 + 71453 = 71524
- 113 + 71411 = 71524
- 137 + 71387 = 71524
- 191 + 71333 = 71524
- 197 + 71327 = 71524
- 263 + 71261 = 71524
Showing the first eight; more decompositions exist.
