Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484396, here are decompositions:

19 + 31484377 = 31484396
37 + 31484359 = 31484396
43 + 31484353 = 31484396
79 + 31484317 = 31484396
157 + 31484239 = 31484396
193 + 31484203 = 31484396
337 + 31484059 = 31484396
439 + 31483957 = 31484396

Showing the first eight; more decompositions exist.
