Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152078, here are decompositions:

37 + 152041 = 152078
61 + 152017 = 152078
109 + 151969 = 152078
139 + 151939 = 152078
181 + 151897 = 152078
229 + 151849 = 152078
307 + 151771 = 152078
349 + 151729 = 152078

Showing the first eight; more decompositions exist.
