Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605044, here are decompositions:

43 + 31605001 = 31605044
181 + 31604863 = 31605044
241 + 31604803 = 31605044
277 + 31604767 = 31605044
313 + 31604731 = 31605044
397 + 31604647 = 31605044
433 + 31604611 = 31605044
487 + 31604557 = 31605044

Showing the first eight; more decompositions exist.
