Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520284, here are decompositions:
- 41 + 31520243 = 31520284
- 83 + 31520201 = 31520284
- 113 + 31520171 = 31520284
- 167 + 31520117 = 31520284
- 347 + 31519937 = 31520284
- 461 + 31519823 = 31520284
- 491 + 31519793 = 31520284
- 683 + 31519601 = 31520284
Showing the first eight; more decompositions exist.
