Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558862, here are decompositions:
- 3 + 31558859 = 31558862
- 19 + 31558843 = 31558862
- 31 + 31558831 = 31558862
- 43 + 31558819 = 31558862
- 73 + 31558789 = 31558862
- 103 + 31558759 = 31558862
- 199 + 31558663 = 31558862
- 229 + 31558633 = 31558862
Showing the first eight; more decompositions exist.
