Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524612, here are decompositions:
- 5 + 31524607 = 31524612
- 43 + 31524569 = 31524612
- 71 + 31524541 = 31524612
- 79 + 31524533 = 31524612
- 89 + 31524523 = 31524612
- 103 + 31524509 = 31524612
- 113 + 31524499 = 31524612
- 193 + 31524419 = 31524612
Showing the first eight; more decompositions exist.
