Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480332, here are decompositions:

43 + 31480289 = 31480332
73 + 31480259 = 31480332
131 + 31480201 = 31480332
229 + 31480103 = 31480332
241 + 31480091 = 31480332
271 + 31480061 = 31480332
283 + 31480049 = 31480332
311 + 31480021 = 31480332

Showing the first eight; more decompositions exist.
