Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480952, here are decompositions:

3 + 31480949 = 31480952
73 + 31480879 = 31480952
79 + 31480873 = 31480952
103 + 31480849 = 31480952
271 + 31480681 = 31480952
313 + 31480639 = 31480952
331 + 31480621 = 31480952
571 + 31480381 = 31480952

Showing the first eight; more decompositions exist.
