Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484324, here are decompositions:

7 + 31484317 = 31484324
43 + 31484281 = 31484324
163 + 31484161 = 31484324
181 + 31484143 = 31484324
367 + 31483957 = 31484324
397 + 31483927 = 31484324
463 + 31483861 = 31484324
523 + 31483801 = 31484324

Showing the first eight; more decompositions exist.
