Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484300, here are decompositions:

19 + 31484281 = 31484300
61 + 31484239 = 31484300
97 + 31484203 = 31484300
139 + 31484161 = 31484300
157 + 31484143 = 31484300
229 + 31484071 = 31484300
241 + 31484059 = 31484300
373 + 31483927 = 31484300

Showing the first eight; more decompositions exist.
