Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488600, here are decompositions:
- 37 + 31488563 = 31488600
- 43 + 31488557 = 31488600
- 53 + 31488547 = 31488600
- 103 + 31488497 = 31488600
- 107 + 31488493 = 31488600
- 131 + 31488469 = 31488600
- 137 + 31488463 = 31488600
- 167 + 31488433 = 31488600
Showing the first eight; more decompositions exist.
