Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460786, here are decompositions:
- 3 + 31460783 = 31460786
- 43 + 31460743 = 31460786
- 109 + 31460677 = 31460786
- 139 + 31460647 = 31460786
- 277 + 31460509 = 31460786
- 373 + 31460413 = 31460786
- 439 + 31460347 = 31460786
- 457 + 31460329 = 31460786
Showing the first eight; more decompositions exist.
