Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494922, here are decompositions:

3 + 31494919 = 31494922
113 + 31494809 = 31494922
233 + 31494689 = 31494922
311 + 31494611 = 31494922
419 + 31494503 = 31494922
443 + 31494479 = 31494922
479 + 31494443 = 31494922
491 + 31494431 = 31494922

Showing the first eight; more decompositions exist.
