Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61178, here are decompositions:

37 + 61141 = 61178
79 + 61099 = 61178
127 + 61051 = 61178
151 + 61027 = 61178
241 + 60937 = 61178
277 + 60901 = 61178
367 + 60811 = 61178
421 + 60757 = 61178

Showing the first eight; more decompositions exist.
