Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493468, here are decompositions:
- 277 + 31493191 = 31493468
- 337 + 31493131 = 31493468
- 421 + 31493047 = 31493468
- 439 + 31493029 = 31493468
- 547 + 31492921 = 31493468
- 619 + 31492849 = 31493468
- 631 + 31492837 = 31493468
- 691 + 31492777 = 31493468
Showing the first eight; more decompositions exist.
