Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522974, here are decompositions:

13 + 31522961 = 31522974
23 + 31522951 = 31522974
37 + 31522937 = 31522974
73 + 31522901 = 31522974
101 + 31522873 = 31522974
127 + 31522847 = 31522974
151 + 31522823 = 31522974
227 + 31522747 = 31522974

Showing the first eight; more decompositions exist.
