Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462870, here are decompositions:
- 59 + 31462811 = 31462870
- 113 + 31462757 = 31462870
- 281 + 31462589 = 31462870
- 293 + 31462577 = 31462870
- 317 + 31462553 = 31462870
- 389 + 31462481 = 31462870
- 419 + 31462451 = 31462870
- 431 + 31462439 = 31462870
Showing the first eight; more decompositions exist.
