Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464646, here are decompositions:
- 29 + 31464617 = 31464646
- 89 + 31464557 = 31464646
- 137 + 31464509 = 31464646
- 503 + 31464143 = 31464646
- 509 + 31464137 = 31464646
- 599 + 31464047 = 31464646
- 683 + 31463963 = 31464646
- 797 + 31463849 = 31464646
Showing the first eight; more decompositions exist.
