Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462860, here are decompositions:
- 29 + 31462831 = 31462860
- 53 + 31462807 = 31462860
- 67 + 31462793 = 31462860
- 89 + 31462771 = 31462860
- 101 + 31462759 = 31462860
- 103 + 31462757 = 31462860
- 109 + 31462751 = 31462860
- 113 + 31462747 = 31462860
Showing the first eight; more decompositions exist.
