Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152072, here are decompositions:

31 + 152041 = 152072
43 + 152029 = 152072
103 + 151969 = 152072
163 + 151909 = 152072
223 + 151849 = 152072
379 + 151693 = 152072
421 + 151651 = 152072
463 + 151609 = 152072

Showing the first eight; more decompositions exist.
