Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151764, here are decompositions:

31 + 151733 = 151764
47 + 151717 = 151764
61 + 151703 = 151764
71 + 151693 = 151764
83 + 151681 = 151764
97 + 151667 = 151764
113 + 151651 = 151764
127 + 151637 = 151764

Showing the first eight; more decompositions exist.
