Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544864, here are decompositions:
- 7 + 31544857 = 31544864
- 37 + 31544827 = 31544864
- 151 + 31544713 = 31544864
- 277 + 31544587 = 31544864
- 313 + 31544551 = 31544864
- 331 + 31544533 = 31544864
- 541 + 31544323 = 31544864
- 643 + 31544221 = 31544864
Showing the first eight; more decompositions exist.
