Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576832, here are decompositions:

73 + 31576759 = 31576832
151 + 31576681 = 31576832
193 + 31576639 = 31576832
283 + 31576549 = 31576832
349 + 31576483 = 31576832
373 + 31576459 = 31576832
379 + 31576453 = 31576832
421 + 31576411 = 31576832

Showing the first eight; more decompositions exist.
