Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547400, here are decompositions:
- 43 + 31547357 = 31547400
- 61 + 31547339 = 31547400
- 83 + 31547317 = 31547400
- 97 + 31547303 = 31547400
- 103 + 31547297 = 31547400
- 113 + 31547287 = 31547400
- 139 + 31547261 = 31547400
- 191 + 31547209 = 31547400
Showing the first eight; more decompositions exist.
