Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540622, here are decompositions:

151 + 31540471 = 31540622
181 + 31540441 = 31540622
283 + 31540339 = 31540622
313 + 31540309 = 31540622
409 + 31540213 = 31540622
433 + 31540189 = 31540622
499 + 31540123 = 31540622
523 + 31540099 = 31540622

Showing the first eight; more decompositions exist.
