Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573694, here are decompositions:

67 + 31573627 = 31573694
73 + 31573621 = 31573694
181 + 31573513 = 31573694
193 + 31573501 = 31573694
331 + 31573363 = 31573694
337 + 31573357 = 31573694
433 + 31573261 = 31573694
541 + 31573153 = 31573694

Showing the first eight; more decompositions exist.
