Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522894, here are decompositions:

5 + 31522889 = 31522894
47 + 31522847 = 31522894
71 + 31522823 = 31522894
281 + 31522613 = 31522894
311 + 31522583 = 31522894
353 + 31522541 = 31522894
401 + 31522493 = 31522894
443 + 31522451 = 31522894

Showing the first eight; more decompositions exist.
