Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496184, here are decompositions:

11 + 31496173 = 31496184
23 + 31496161 = 31496184
43 + 31496141 = 31496184
61 + 31496123 = 31496184
101 + 31496083 = 31496184
127 + 31496057 = 31496184
157 + 31496027 = 31496184
173 + 31496011 = 31496184

Showing the first eight; more decompositions exist.
