Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461718, here are decompositions:
- 149 + 31461569 = 31461718
- 557 + 31461161 = 31461718
- 569 + 31461149 = 31461718
- 839 + 31460879 = 31461718
- 881 + 31460837 = 31461718
- 887 + 31460831 = 31461718
- 1061 + 31460657 = 31461718
- 1109 + 31460609 = 31461718
Showing the first eight; more decompositions exist.
