Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456622, here are decompositions:

181 + 31456441 = 31456622
193 + 31456429 = 31456622
331 + 31456291 = 31456622
499 + 31456123 = 31456622
523 + 31456099 = 31456622
601 + 31456021 = 31456622
619 + 31456003 = 31456622
661 + 31455961 = 31456622

Showing the first eight; more decompositions exist.
