Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137580, here are decompositions:
- 7 + 137573 = 137580
- 13 + 137567 = 137580
- 43 + 137537 = 137580
- 61 + 137519 = 137580
- 73 + 137507 = 137580
- 89 + 137491 = 137580
- 97 + 137483 = 137580
- 103 + 137477 = 137580
Showing the first eight; more decompositions exist.
