Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551044, here are decompositions:

67 + 31550977 = 31551044
97 + 31550947 = 31551044
193 + 31550851 = 31551044
211 + 31550833 = 31551044
241 + 31550803 = 31551044
313 + 31550731 = 31551044
373 + 31550671 = 31551044
433 + 31550611 = 31551044

Showing the first eight; more decompositions exist.
