Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971540, here are decompositions:
- 19 + 971521 = 971540
- 61 + 971479 = 971540
- 67 + 971473 = 971540
- 139 + 971401 = 971540
- 151 + 971389 = 971540
- 277 + 971263 = 971540
- 397 + 971143 = 971540
- 463 + 971077 = 971540
Showing the first eight; more decompositions exist.
