Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522184, here are decompositions:

3 + 31522181 = 31522184
163 + 31522021 = 31522184
193 + 31521991 = 31522184
541 + 31521643 = 31522184
613 + 31521571 = 31522184
643 + 31521541 = 31522184
751 + 31521433 = 31522184
1153 + 31521031 = 31522184

Showing the first eight; more decompositions exist.
