Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37640, here are decompositions:
- 7 + 37633 = 37640
- 61 + 37579 = 37640
- 67 + 37573 = 37640
- 73 + 37567 = 37640
- 79 + 37561 = 37640
- 103 + 37537 = 37640
- 139 + 37501 = 37640
- 151 + 37489 = 37640
Showing the first eight; more decompositions exist.
