Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550546, here are decompositions:

3 + 31550543 = 31550546
7 + 31550539 = 31550546
37 + 31550509 = 31550546
67 + 31550479 = 31550546
109 + 31550437 = 31550546
193 + 31550353 = 31550546
367 + 31550179 = 31550546
397 + 31550149 = 31550546

Showing the first eight; more decompositions exist.
