Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484294, here are decompositions:

13 + 31484281 = 31484294
151 + 31484143 = 31484294
223 + 31484071 = 31484294
313 + 31483981 = 31484294
337 + 31483957 = 31484294
367 + 31483927 = 31484294
433 + 31483861 = 31484294
487 + 31483807 = 31484294

Showing the first eight; more decompositions exist.
