Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513136, here are decompositions:
- 13 + 31513123 = 31513136
- 19 + 31513117 = 31513136
- 73 + 31513063 = 31513136
- 79 + 31513057 = 31513136
- 103 + 31513033 = 31513136
- 139 + 31512997 = 31513136
- 223 + 31512913 = 31513136
- 229 + 31512907 = 31513136
Showing the first eight; more decompositions exist.
