Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591622, here are decompositions:

19 + 31591603 = 31591622
109 + 31591513 = 31591622
241 + 31591381 = 31591622
331 + 31591291 = 31591622
373 + 31591249 = 31591622
463 + 31591159 = 31591622
523 + 31591099 = 31591622
613 + 31591009 = 31591622

Showing the first eight; more decompositions exist.
