Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146072, here are decompositions:

13 + 146059 = 146072
61 + 146011 = 146072
103 + 145969 = 146072
109 + 145963 = 146072
139 + 145933 = 146072
193 + 145879 = 146072
211 + 145861 = 146072
313 + 145759 = 146072

Showing the first eight; more decompositions exist.
