Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506552, here are decompositions:

23 + 31506529 = 31506552
29 + 31506523 = 31506552
31 + 31506521 = 31506552
41 + 31506511 = 31506552
73 + 31506479 = 31506552
109 + 31506443 = 31506552
131 + 31506421 = 31506552
179 + 31506373 = 31506552

Showing the first eight; more decompositions exist.
