Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583052, here are decompositions:

5 + 31583047 = 31583052
19 + 31583033 = 31583052
29 + 31583023 = 31583052
71 + 31582981 = 31583052
101 + 31582951 = 31583052
103 + 31582949 = 31583052
139 + 31582913 = 31583052
229 + 31582823 = 31583052

Showing the first eight; more decompositions exist.
