Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456590, here are decompositions:
- 43 + 31456547 = 31456590
- 59 + 31456531 = 31456590
- 73 + 31456517 = 31456590
- 89 + 31456501 = 31456590
- 103 + 31456487 = 31456590
- 149 + 31456441 = 31456590
- 211 + 31456379 = 31456590
- 229 + 31456361 = 31456590
Showing the first eight; more decompositions exist.
