Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489610, here are decompositions:

193 + 31489417 = 31489610
199 + 31489411 = 31489610
211 + 31489399 = 31489610
331 + 31489279 = 31489610
367 + 31489243 = 31489610
433 + 31489177 = 31489610
463 + 31489147 = 31489610
541 + 31489069 = 31489610

Showing the first eight; more decompositions exist.
