Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485626, here are decompositions:

43 + 31485583 = 31485626
199 + 31485427 = 31485626
229 + 31485397 = 31485626
307 + 31485319 = 31485626
313 + 31485313 = 31485626
349 + 31485277 = 31485626
379 + 31485247 = 31485626
433 + 31485193 = 31485626

Showing the first eight; more decompositions exist.
