Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582934, here are decompositions:

3 + 31582931 = 31582934
37 + 31582897 = 31582934
43 + 31582891 = 31582934
157 + 31582777 = 31582934
307 + 31582627 = 31582934
421 + 31582513 = 31582934
463 + 31582471 = 31582934
601 + 31582333 = 31582934

Showing the first eight; more decompositions exist.
