Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513250, here are decompositions:
- 31 + 31513219 = 31513250
- 37 + 31513213 = 31513250
- 103 + 31513147 = 31513250
- 127 + 31513123 = 31513250
- 193 + 31513057 = 31513250
- 337 + 31512913 = 31513250
- 409 + 31512841 = 31513250
- 547 + 31512703 = 31513250
Showing the first eight; more decompositions exist.
