Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573436, here are decompositions:

43 + 31573393 = 31573436
73 + 31573363 = 31573436
79 + 31573357 = 31573436
157 + 31573279 = 31573436
283 + 31573153 = 31573436
313 + 31573123 = 31573436
379 + 31573057 = 31573436
409 + 31573027 = 31573436

Showing the first eight; more decompositions exist.
