Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542034, here are decompositions:

3 + 31542031 = 31542034
11 + 31542023 = 31542034
23 + 31542011 = 31542034
53 + 31541981 = 31542034
101 + 31541933 = 31542034
131 + 31541903 = 31542034
383 + 31541651 = 31542034
401 + 31541633 = 31542034

Showing the first eight; more decompositions exist.
