Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71522, here are decompositions:
- 19 + 71503 = 71522
- 43 + 71479 = 71522
- 79 + 71443 = 71522
- 103 + 71419 = 71522
- 109 + 71413 = 71522
- 163 + 71359 = 71522
- 181 + 71341 = 71522
- 193 + 71329 = 71522
Showing the first eight; more decompositions exist.
