Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484994, here are decompositions:

5 + 31484989 = 31484994
53 + 31484941 = 31484994
83 + 31484911 = 31484994
131 + 31484863 = 31484994
157 + 31484837 = 31484994
173 + 31484821 = 31484994
193 + 31484801 = 31484994
197 + 31484797 = 31484994

Showing the first eight; more decompositions exist.
