Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483430, here are decompositions:

61 + 31483369 = 31483430
79 + 31483351 = 31483430
103 + 31483327 = 31483430
193 + 31483237 = 31483430
313 + 31483117 = 31483430
337 + 31483093 = 31483430
379 + 31483051 = 31483430
439 + 31482991 = 31483430

Showing the first eight; more decompositions exist.
