Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573586, here are decompositions:

3 + 31573583 = 31573586
73 + 31573513 = 31573586
193 + 31573393 = 31573586
223 + 31573363 = 31573586
229 + 31573357 = 31573586
307 + 31573279 = 31573586
397 + 31573189 = 31573586
433 + 31573153 = 31573586

Showing the first eight; more decompositions exist.
