Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619946, here are decompositions:

97 + 31619849 = 31619946
103 + 31619843 = 31619946
139 + 31619807 = 31619946
157 + 31619789 = 31619946
223 + 31619723 = 31619946
229 + 31619717 = 31619946
233 + 31619713 = 31619946
263 + 31619683 = 31619946

Showing the first eight; more decompositions exist.
