Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530092, here are decompositions:

31 + 31530061 = 31530092
193 + 31529899 = 31530092
211 + 31529881 = 31530092
421 + 31529671 = 31530092
463 + 31529629 = 31530092
499 + 31529593 = 31530092
541 + 31529551 = 31530092
571 + 31529521 = 31530092

Showing the first eight; more decompositions exist.
