Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523698, here are decompositions:

29 + 31523669 = 31523698
47 + 31523651 = 31523698
257 + 31523441 = 31523698
317 + 31523381 = 31523698
389 + 31523309 = 31523698
419 + 31523279 = 31523698
431 + 31523267 = 31523698
461 + 31523237 = 31523698

Showing the first eight; more decompositions exist.
