Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474550, here are decompositions:
- 31 + 31474519 = 31474550
- 61 + 31474489 = 31474550
- 127 + 31474423 = 31474550
- 193 + 31474357 = 31474550
- 199 + 31474351 = 31474550
- 337 + 31474213 = 31474550
- 379 + 31474171 = 31474550
- 409 + 31474141 = 31474550
Showing the first eight; more decompositions exist.
