Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463574, here are decompositions:
- 41 + 31463533 = 31463574
- 47 + 31463527 = 31463574
- 67 + 31463507 = 31463574
- 97 + 31463477 = 31463574
- 167 + 31463407 = 31463574
- 211 + 31463363 = 31463574
- 257 + 31463317 = 31463574
- 293 + 31463281 = 31463574
Showing the first eight; more decompositions exist.
