Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463272, here are decompositions:
- 3 + 31463269 = 31463272
- 11 + 31463261 = 31463272
- 23 + 31463249 = 31463272
- 59 + 31463213 = 31463272
- 149 + 31463123 = 31463272
- 173 + 31463099 = 31463272
- 293 + 31462979 = 31463272
- 383 + 31462889 = 31463272
Showing the first eight; more decompositions exist.
