Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449092, here are decompositions:

193 + 31448899 = 31449092
229 + 31448863 = 31449092
271 + 31448821 = 31449092
373 + 31448719 = 31449092
379 + 31448713 = 31449092
541 + 31448551 = 31449092
613 + 31448479 = 31449092
643 + 31448449 = 31449092

Showing the first eight; more decompositions exist.
