Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493352, here are decompositions:

5 + 31493347 = 31493352
13 + 31493339 = 31493352
29 + 31493323 = 31493352
31 + 31493321 = 31493352
61 + 31493291 = 31493352
101 + 31493251 = 31493352
103 + 31493249 = 31493352
151 + 31493201 = 31493352

Showing the first eight; more decompositions exist.
