Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542406, here are decompositions:

29 + 31542377 = 31542406
47 + 31542359 = 31542406
83 + 31542323 = 31542406
173 + 31542233 = 31542406
257 + 31542149 = 31542406
293 + 31542113 = 31542406
383 + 31542023 = 31542406
503 + 31541903 = 31542406

Showing the first eight; more decompositions exist.
