Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542082, here are decompositions:

59 + 31542023 = 31542082
71 + 31542011 = 31542082
101 + 31541981 = 31542082
149 + 31541933 = 31542082
179 + 31541903 = 31542082
191 + 31541891 = 31542082
389 + 31541693 = 31542082
431 + 31541651 = 31542082

Showing the first eight; more decompositions exist.
