Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535192, here are decompositions:
- 19 + 31535173 = 31535192
- 61 + 31535131 = 31535192
- 79 + 31535113 = 31535192
- 109 + 31535083 = 31535192
- 181 + 31535011 = 31535192
- 193 + 31534999 = 31535192
- 211 + 31534981 = 31535192
- 313 + 31534879 = 31535192
Showing the first eight; more decompositions exist.
