Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158072, here are decompositions:

43 + 158029 = 158072
73 + 157999 = 158072
139 + 157933 = 158072
241 + 157831 = 158072
433 + 157639 = 158072
643 + 157429 = 158072
661 + 157411 = 158072
709 + 157363 = 158072

Showing the first eight; more decompositions exist.
