Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591324, here are decompositions:

137 + 31591187 = 31591324
257 + 31591067 = 31591324
263 + 31591061 = 31591324
293 + 31591031 = 31591324
311 + 31591013 = 31591324
383 + 31590941 = 31591324
431 + 31590893 = 31591324
491 + 31590833 = 31591324

Showing the first eight; more decompositions exist.
