Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542076, here are decompositions:

53 + 31542023 = 31542076
173 + 31541903 = 31542076
383 + 31541693 = 31542076
443 + 31541633 = 31542076
479 + 31541597 = 31542076
569 + 31541507 = 31542076
593 + 31541483 = 31542076
647 + 31541429 = 31542076

Showing the first eight; more decompositions exist.
