Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472810, here are decompositions:
- 3 + 31472807 = 31472810
- 37 + 31472773 = 31472810
- 199 + 31472611 = 31472810
- 223 + 31472587 = 31472810
- 331 + 31472479 = 31472810
- 373 + 31472437 = 31472810
- 571 + 31472239 = 31472810
- 601 + 31472209 = 31472810
Showing the first eight; more decompositions exist.
