Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61158, here are decompositions:

5 + 61153 = 61158
7 + 61151 = 61158
17 + 61141 = 61158
29 + 61129 = 61158
37 + 61121 = 61158
59 + 61099 = 61158
67 + 61091 = 61158
101 + 61057 = 61158

Showing the first eight; more decompositions exist.
