Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147918, here are decompositions:

37 + 147881 = 147918
59 + 147859 = 147918
107 + 147811 = 147918
131 + 147787 = 147918
139 + 147779 = 147918
149 + 147769 = 147918
157 + 147761 = 147918
179 + 147739 = 147918

Showing the first eight; more decompositions exist.
