Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505026, here are decompositions:

23 + 31505003 = 31505026
83 + 31504943 = 31505026
227 + 31504799 = 31505026
359 + 31504667 = 31505026
419 + 31504607 = 31505026
479 + 31504547 = 31505026
587 + 31504439 = 31505026
653 + 31504373 = 31505026

Showing the first eight; more decompositions exist.
