Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610554, here are decompositions:

191 + 31610363 = 31610554
263 + 31610291 = 31610554
317 + 31610237 = 31610554
383 + 31610171 = 31610554
461 + 31610093 = 31610554
491 + 31610063 = 31610554
587 + 31609967 = 31610554
617 + 31609937 = 31610554

Showing the first eight; more decompositions exist.
