Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480348, here are decompositions:

59 + 31480289 = 31480348
89 + 31480259 = 31480348
257 + 31480091 = 31480348
269 + 31480079 = 31480348
401 + 31479947 = 31480348
467 + 31479881 = 31480348
491 + 31479857 = 31480348
677 + 31479671 = 31480348

Showing the first eight; more decompositions exist.
