Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612582, here are decompositions:

101 + 31612481 = 31612582
191 + 31612391 = 31612582
269 + 31612313 = 31612582
359 + 31612223 = 31612582
383 + 31612199 = 31612582
431 + 31612151 = 31612582
461 + 31612121 = 31612582
503 + 31612079 = 31612582

Showing the first eight; more decompositions exist.
