Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522034, here are decompositions:

13 + 31522021 = 31522034
43 + 31521991 = 31522034
151 + 31521883 = 31522034
241 + 31521793 = 31522034
367 + 31521667 = 31522034
463 + 31521571 = 31522034
601 + 31521433 = 31522034
811 + 31521223 = 31522034

Showing the first eight; more decompositions exist.
