Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524648, here are decompositions:
- 5 + 31524643 = 31524648
- 7 + 31524641 = 31524648
- 41 + 31524607 = 31524648
- 61 + 31524587 = 31524648
- 79 + 31524569 = 31524648
- 107 + 31524541 = 31524648
- 131 + 31524517 = 31524648
- 139 + 31524509 = 31524648
Showing the first eight; more decompositions exist.
