Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468976, here are decompositions:
- 13 + 31468963 = 31468976
- 73 + 31468903 = 31468976
- 127 + 31468849 = 31468976
- 199 + 31468777 = 31468976
- 277 + 31468699 = 31468976
- 379 + 31468597 = 31468976
- 433 + 31468543 = 31468976
- 523 + 31468453 = 31468976
Showing the first eight; more decompositions exist.
