Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524744, here are decompositions:
- 23 + 31524721 = 31524744
- 67 + 31524677 = 31524744
- 71 + 31524673 = 31524744
- 101 + 31524643 = 31524744
- 103 + 31524641 = 31524744
- 137 + 31524607 = 31524744
- 157 + 31524587 = 31524744
- 211 + 31524533 = 31524744
Showing the first eight; more decompositions exist.
