Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620058, here are decompositions:

251 + 31619807 = 31620058
257 + 31619801 = 31620058
269 + 31619789 = 31620058
317 + 31619741 = 31620058
389 + 31619669 = 31620058
557 + 31619501 = 31620058
599 + 31619459 = 31620058
797 + 31619261 = 31620058

Showing the first eight; more decompositions exist.
