Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147144, here are decompositions:

5 + 147139 = 147144
7 + 147137 = 147144
37 + 147107 = 147144
47 + 147097 = 147144
61 + 147083 = 147144
71 + 147073 = 147144
97 + 147047 = 147144
113 + 147031 = 147144

Showing the first eight; more decompositions exist.
