Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131372, here are decompositions:

61 + 131311 = 131372
79 + 131293 = 131372
151 + 131221 = 131372
223 + 131149 = 131372
229 + 131143 = 131372
271 + 131101 = 131372
313 + 131059 = 131372
331 + 131041 = 131372

Showing the first eight; more decompositions exist.
