Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71478, here are decompositions:
- 5 + 71473 = 71478
- 7 + 71471 = 71478
- 41 + 71437 = 71478
- 59 + 71419 = 71478
- 67 + 71411 = 71478
- 79 + 71399 = 71478
- 89 + 71389 = 71478
- 131 + 71347 = 71478
Showing the first eight; more decompositions exist.
