Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482242, here are decompositions:

13 + 31482229 = 31482242
73 + 31482169 = 31482242
139 + 31482103 = 31482242
199 + 31482043 = 31482242
229 + 31482013 = 31482242
331 + 31481911 = 31482242
499 + 31481743 = 31482242
541 + 31481701 = 31482242

Showing the first eight; more decompositions exist.
