Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582994, here are decompositions:

13 + 31582981 = 31582994
43 + 31582951 = 31582994
97 + 31582897 = 31582994
103 + 31582891 = 31582994
367 + 31582627 = 31582994
463 + 31582531 = 31582994
523 + 31582471 = 31582994
577 + 31582417 = 31582994

Showing the first eight; more decompositions exist.
