Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551092, here are decompositions:

3 + 31551089 = 31551092
73 + 31551019 = 31551092
241 + 31550851 = 31551092
421 + 31550671 = 31551092
499 + 31550593 = 31551092
523 + 31550569 = 31551092
613 + 31550479 = 31551092
631 + 31550461 = 31551092

Showing the first eight; more decompositions exist.
