Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71572, here are decompositions:
- 3 + 71569 = 71572
- 23 + 71549 = 71572
- 89 + 71483 = 71572
- 101 + 71471 = 71572
- 173 + 71399 = 71572
- 233 + 71339 = 71572
- 239 + 71333 = 71572
- 311 + 71261 = 71572
Showing the first eight; more decompositions exist.
