Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152138, here are decompositions:

61 + 152077 = 152138
97 + 152041 = 152138
109 + 152029 = 152138
199 + 151939 = 152138
229 + 151909 = 152138
241 + 151897 = 152138
367 + 151771 = 152138
409 + 151729 = 152138

Showing the first eight; more decompositions exist.
