Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550346, here are decompositions:

7 + 31550339 = 31550346
17 + 31550329 = 31550346
19 + 31550327 = 31550346
59 + 31550287 = 31550346
89 + 31550257 = 31550346
167 + 31550179 = 31550346
193 + 31550153 = 31550346
197 + 31550149 = 31550346

Showing the first eight; more decompositions exist.
