Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550996, here are decompositions:

3 + 31550993 = 31550996
19 + 31550977 = 31550996
73 + 31550923 = 31550996
163 + 31550833 = 31550996
193 + 31550803 = 31550996
199 + 31550797 = 31550996
397 + 31550599 = 31550996
409 + 31550587 = 31550996

Showing the first eight; more decompositions exist.
