Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590236, here are decompositions:

103 + 31590133 = 31590236
199 + 31590037 = 31590236
229 + 31590007 = 31590236
283 + 31589953 = 31590236
313 + 31589923 = 31590236
367 + 31589869 = 31590236
409 + 31589827 = 31590236
463 + 31589773 = 31590236

Showing the first eight; more decompositions exist.
