Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460520, here are decompositions:
- 11 + 31460509 = 31460520
- 23 + 31460497 = 31460520
- 29 + 31460491 = 31460520
- 37 + 31460483 = 31460520
- 79 + 31460441 = 31460520
- 89 + 31460431 = 31460520
- 107 + 31460413 = 31460520
- 151 + 31460369 = 31460520
Showing the first eight; more decompositions exist.
