Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972540, here are decompositions:
- 7 + 972533 = 972540
- 47 + 972493 = 972540
- 59 + 972481 = 972540
- 67 + 972473 = 972540
- 71 + 972469 = 972540
- 97 + 972443 = 972540
- 109 + 972431 = 972540
- 113 + 972427 = 972540
Showing the first eight; more decompositions exist.
