Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583236, here are decompositions:

89 + 31583147 = 31583236
149 + 31583087 = 31583236
389 + 31582847 = 31583236
479 + 31582757 = 31583236
557 + 31582679 = 31583236
563 + 31582673 = 31583236
569 + 31582667 = 31583236
647 + 31582589 = 31583236

Showing the first eight; more decompositions exist.
