Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574036, here are decompositions:
- 37 + 31573999 = 31574036
- 79 + 31573957 = 31574036
- 283 + 31573753 = 31574036
- 397 + 31573639 = 31574036
- 409 + 31573627 = 31574036
- 523 + 31573513 = 31574036
- 643 + 31573393 = 31574036
- 673 + 31573363 = 31574036
Showing the first eight; more decompositions exist.
