Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91242, here are decompositions:

5 + 91237 = 91242
13 + 91229 = 91242
43 + 91199 = 91242
59 + 91183 = 91242
79 + 91163 = 91242
83 + 91159 = 91242
89 + 91153 = 91242
101 + 91141 = 91242

Showing the first eight; more decompositions exist.
