Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542004, here are decompositions:

3 + 31542001 = 31542004
23 + 31541981 = 31542004
71 + 31541933 = 31542004
101 + 31541903 = 31542004
113 + 31541891 = 31542004
311 + 31541693 = 31542004
353 + 31541651 = 31542004
521 + 31541483 = 31542004

Showing the first eight; more decompositions exist.
