Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522754, here are decompositions:

7 + 31522747 = 31522754
37 + 31522717 = 31522754
61 + 31522693 = 31522754
97 + 31522657 = 31522754
157 + 31522597 = 31522754
163 + 31522591 = 31522754
313 + 31522441 = 31522754
397 + 31522357 = 31522754

Showing the first eight; more decompositions exist.
