Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540498, here are decompositions:

5 + 31540493 = 31540498
257 + 31540241 = 31540498
281 + 31540217 = 31540498
317 + 31540181 = 31540498
389 + 31540109 = 31540498
467 + 31540031 = 31540498
491 + 31540007 = 31540498
641 + 31539857 = 31540498

Showing the first eight; more decompositions exist.
