Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482086, here are decompositions:

3 + 31482083 = 31482086
19 + 31482067 = 31482086
43 + 31482043 = 31482086
73 + 31482013 = 31482086
199 + 31481887 = 31482086
373 + 31481713 = 31482086
409 + 31481677 = 31482086
463 + 31481623 = 31482086

Showing the first eight; more decompositions exist.
