Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573796, here are decompositions:

3 + 31573793 = 31573796
43 + 31573753 = 31573796
157 + 31573639 = 31573796
283 + 31573513 = 31573796
433 + 31573363 = 31573796
439 + 31573357 = 31573796
607 + 31573189 = 31573796
643 + 31573153 = 31573796

Showing the first eight; more decompositions exist.
