Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25130, here are decompositions:
- 3 + 25127 = 25130
- 13 + 25117 = 25130
- 19 + 25111 = 25130
- 43 + 25087 = 25130
- 73 + 25057 = 25130
- 97 + 25033 = 25130
- 151 + 24979 = 25130
- 163 + 24967 = 25130
Showing the first eight; more decompositions exist.
