Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547376, here are decompositions:
- 19 + 31547357 = 31547376
- 37 + 31547339 = 31547376
- 59 + 31547317 = 31547376
- 73 + 31547303 = 31547376
- 79 + 31547297 = 31547376
- 89 + 31547287 = 31547376
- 109 + 31547267 = 31547376
- 167 + 31547209 = 31547376
Showing the first eight; more decompositions exist.
