Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482542, here are decompositions:

31 + 31482511 = 31482542
43 + 31482499 = 31482542
103 + 31482439 = 31482542
193 + 31482349 = 31482542
199 + 31482343 = 31482542
271 + 31482271 = 31482542
313 + 31482229 = 31482542
373 + 31482169 = 31482542

Showing the first eight; more decompositions exist.
