Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152940, here are decompositions:

31 + 152909 = 152940
41 + 152899 = 152940
43 + 152897 = 152940
61 + 152879 = 152940
83 + 152857 = 152940
89 + 152851 = 152940
97 + 152843 = 152940
101 + 152839 = 152940

Showing the first eight; more decompositions exist.
