Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71472, here are decompositions:
- 19 + 71453 = 71472
- 29 + 71443 = 71472
- 43 + 71429 = 71472
- 53 + 71419 = 71472
- 59 + 71413 = 71472
- 61 + 71411 = 71472
- 73 + 71399 = 71472
- 83 + 71389 = 71472
Showing the first eight; more decompositions exist.
