Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522830, here are decompositions:

7 + 31522823 = 31522830
83 + 31522747 = 31522830
113 + 31522717 = 31522830
137 + 31522693 = 31522830
167 + 31522663 = 31522830
173 + 31522657 = 31522830
197 + 31522633 = 31522830
233 + 31522597 = 31522830

Showing the first eight; more decompositions exist.
