Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552072, here are decompositions:

3 + 31552069 = 31552072
23 + 31552049 = 31552072
53 + 31552019 = 31552072
113 + 31551959 = 31552072
131 + 31551941 = 31552072
269 + 31551803 = 31552072
389 + 31551683 = 31552072
401 + 31551671 = 31552072

Showing the first eight; more decompositions exist.
