Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553710, here are decompositions:

3 + 31553707 = 31553710
47 + 31553663 = 31553710
101 + 31553609 = 31553710
191 + 31553519 = 31553710
257 + 31553453 = 31553710
359 + 31553351 = 31553710
389 + 31553321 = 31553710
431 + 31553279 = 31553710

Showing the first eight; more decompositions exist.
