Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71480, here are decompositions:
- 7 + 71473 = 71480
- 37 + 71443 = 71480
- 43 + 71437 = 71480
- 61 + 71419 = 71480
- 67 + 71413 = 71480
- 127 + 71353 = 71480
- 139 + 71341 = 71480
- 151 + 71329 = 71480
Showing the first eight; more decompositions exist.
