Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462600, here are decompositions:
- 11 + 31462589 = 31462600
- 17 + 31462583 = 31462600
- 23 + 31462577 = 31462600
- 47 + 31462553 = 31462600
- 53 + 31462547 = 31462600
- 149 + 31462451 = 31462600
- 167 + 31462433 = 31462600
- 227 + 31462373 = 31462600
Showing the first eight; more decompositions exist.
