Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471298, here are decompositions:

127 + 31471171 = 31471298
151 + 31471147 = 31471298
307 + 31470991 = 31471298
409 + 31470889 = 31471298
499 + 31470799 = 31471298
577 + 31470721 = 31471298
751 + 31470547 = 31471298
829 + 31470469 = 31471298

Showing the first eight; more decompositions exist.
