Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493826, here are decompositions:
- 5 + 31493821 = 31493826
- 37 + 31493789 = 31493826
- 43 + 31493783 = 31493826
- 47 + 31493779 = 31493826
- 83 + 31493743 = 31493826
- 109 + 31493717 = 31493826
- 137 + 31493689 = 31493826
- 149 + 31493677 = 31493826
Showing the first eight; more decompositions exist.
