Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498200, here are decompositions:
- 7 + 31498193 = 31498200
- 11 + 31498189 = 31498200
- 89 + 31498111 = 31498200
- 113 + 31498087 = 31498200
- 131 + 31498069 = 31498200
- 157 + 31498043 = 31498200
- 191 + 31498009 = 31498200
- 193 + 31498007 = 31498200
Showing the first eight; more decompositions exist.
