Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40130, here are decompositions:
- 3 + 40127 = 40130
- 7 + 40123 = 40130
- 19 + 40111 = 40130
- 31 + 40099 = 40130
- 37 + 40093 = 40130
- 43 + 40087 = 40130
- 67 + 40063 = 40130
- 151 + 39979 = 40130
Showing the first eight; more decompositions exist.
