Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551082, here are decompositions:

11 + 31551071 = 31551082
71 + 31551011 = 31551082
83 + 31550999 = 31551082
89 + 31550993 = 31551082
281 + 31550801 = 31551082
359 + 31550723 = 31551082
383 + 31550699 = 31551082
401 + 31550681 = 31551082

Showing the first eight; more decompositions exist.
