Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590452, here are decompositions:

31 + 31590421 = 31590452
109 + 31590343 = 31590452
139 + 31590313 = 31590452
211 + 31590241 = 31590452
241 + 31590211 = 31590452
331 + 31590121 = 31590452
499 + 31589953 = 31590452
769 + 31589683 = 31590452

Showing the first eight; more decompositions exist.
