Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468500, here are decompositions:
- 29 + 31468471 = 31468500
- 47 + 31468453 = 31468500
- 53 + 31468447 = 31468500
- 97 + 31468403 = 31468500
- 101 + 31468399 = 31468500
- 103 + 31468397 = 31468500
- 109 + 31468391 = 31468500
- 131 + 31468369 = 31468500
Showing the first eight; more decompositions exist.
