Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520276, here are decompositions:

43 + 31520233 = 31520276
97 + 31520179 = 31520276
103 + 31520173 = 31520276
157 + 31520119 = 31520276
349 + 31519927 = 31520276
367 + 31519909 = 31520276
433 + 31519843 = 31520276
439 + 31519837 = 31520276

Showing the first eight; more decompositions exist.
