Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482982, here are decompositions:

5 + 31482977 = 31482982
149 + 31482833 = 31482982
239 + 31482743 = 31482982
383 + 31482599 = 31482982
431 + 31482551 = 31482982
593 + 31482389 = 31482982
701 + 31482281 = 31482982
809 + 31482173 = 31482982

Showing the first eight; more decompositions exist.
