Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464430, here are decompositions:
- 3 + 31464427 = 31464430
- 29 + 31464401 = 31464430
- 71 + 31464359 = 31464430
- 89 + 31464341 = 31464430
- 149 + 31464281 = 31464430
- 197 + 31464233 = 31464430
- 281 + 31464149 = 31464430
- 293 + 31464137 = 31464430
Showing the first eight; more decompositions exist.
