Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483412, here are decompositions:

43 + 31483369 = 31483412
61 + 31483351 = 31483412
151 + 31483261 = 31483412
199 + 31483213 = 31483412
409 + 31483003 = 31483412
421 + 31482991 = 31483412
439 + 31482973 = 31483412
523 + 31482889 = 31483412

Showing the first eight; more decompositions exist.
