Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490424, here are decompositions:
- 41 + 31490383 = 31490424
- 47 + 31490377 = 31490424
- 61 + 31490363 = 31490424
- 73 + 31490351 = 31490424
- 101 + 31490323 = 31490424
- 127 + 31490297 = 31490424
- 137 + 31490287 = 31490424
- 167 + 31490257 = 31490424
Showing the first eight; more decompositions exist.
