Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606044, here are decompositions:

61 + 31605983 = 31606044
73 + 31605971 = 31606044
131 + 31605913 = 31606044
167 + 31605877 = 31606044
233 + 31605811 = 31606044
241 + 31605803 = 31606044
263 + 31605781 = 31606044
271 + 31605773 = 31606044

Showing the first eight; more decompositions exist.
