Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522954, here are decompositions:

3 + 31522951 = 31522954
17 + 31522937 = 31522954
53 + 31522901 = 31522954
107 + 31522847 = 31522954
131 + 31522823 = 31522954
401 + 31522553 = 31522954
431 + 31522523 = 31522954
461 + 31522493 = 31522954

Showing the first eight; more decompositions exist.
