Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484150, here are decompositions:

7 + 31484143 = 31484150
79 + 31484071 = 31484150
193 + 31483957 = 31484150
223 + 31483927 = 31484150
331 + 31483819 = 31484150
349 + 31483801 = 31484150
487 + 31483663 = 31484150
601 + 31483549 = 31484150

Showing the first eight; more decompositions exist.
