Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509092, here are decompositions:

31 + 31509061 = 31509092
61 + 31509031 = 31509092
229 + 31508863 = 31509092
379 + 31508713 = 31509092
409 + 31508683 = 31509092
421 + 31508671 = 31509092
523 + 31508569 = 31509092
631 + 31508461 = 31509092

Showing the first eight; more decompositions exist.
