Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484348, here are decompositions:

31 + 31484317 = 31484348
67 + 31484281 = 31484348
109 + 31484239 = 31484348
139 + 31484209 = 31484348
277 + 31484071 = 31484348
367 + 31483981 = 31484348
421 + 31483927 = 31484348
487 + 31483861 = 31484348

Showing the first eight; more decompositions exist.
