Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506590, here are decompositions:
- 13 + 31506577 = 31506590
- 61 + 31506529 = 31506590
- 67 + 31506523 = 31506590
- 79 + 31506511 = 31506590
- 223 + 31506367 = 31506590
- 307 + 31506283 = 31506590
- 397 + 31506193 = 31506590
- 487 + 31506103 = 31506590
Showing the first eight; more decompositions exist.
