Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474742, here are decompositions:
- 73 + 31474669 = 31474742
- 193 + 31474549 = 31474742
- 223 + 31474519 = 31474742
- 241 + 31474501 = 31474742
- 379 + 31474363 = 31474742
- 571 + 31474171 = 31474742
- 601 + 31474141 = 31474742
- 613 + 31474129 = 31474742
Showing the first eight; more decompositions exist.
