Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577318, here are decompositions:
- 79 + 31577239 = 31577318
- 109 + 31577209 = 31577318
- 541 + 31576777 = 31577318
- 739 + 31576579 = 31577318
- 769 + 31576549 = 31577318
- 859 + 31576459 = 31577318
- 907 + 31576411 = 31577318
- 967 + 31576351 = 31577318
Showing the first eight; more decompositions exist.
