Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71378, here are decompositions:
- 19 + 71359 = 71378
- 31 + 71347 = 71378
- 37 + 71341 = 71378
- 61 + 71317 = 71378
- 211 + 71167 = 71378
- 367 + 71011 = 71378
- 379 + 70999 = 71378
- 397 + 70981 = 71378
Showing the first eight; more decompositions exist.
