Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542010, here are decompositions:

29 + 31541981 = 31542010
107 + 31541903 = 31542010
317 + 31541693 = 31542010
359 + 31541651 = 31542010
419 + 31541591 = 31542010
503 + 31541507 = 31542010
593 + 31541417 = 31542010
743 + 31541267 = 31542010

Showing the first eight; more decompositions exist.
