Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553734, here are decompositions:

5 + 31553729 = 31553734
71 + 31553663 = 31553734
281 + 31553453 = 31553734
347 + 31553387 = 31553734
383 + 31553351 = 31553734
461 + 31553273 = 31553734
521 + 31553213 = 31553734
557 + 31553177 = 31553734

Showing the first eight; more decompositions exist.
