Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484946, here are decompositions:

5 + 31484941 = 31484946
43 + 31484903 = 31484946
83 + 31484863 = 31484946
107 + 31484839 = 31484946
109 + 31484837 = 31484946
149 + 31484797 = 31484946
193 + 31484753 = 31484946
433 + 31484513 = 31484946

Showing the first eight; more decompositions exist.
