Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546872, here are decompositions:
- 11 + 31546861 = 31546872
- 29 + 31546843 = 31546872
- 41 + 31546831 = 31546872
- 59 + 31546813 = 31546872
- 73 + 31546799 = 31546872
- 83 + 31546789 = 31546872
- 113 + 31546759 = 31546872
- 131 + 31546741 = 31546872
Showing the first eight; more decompositions exist.
