Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592284, here are decompositions:

71 + 31592213 = 31592284
233 + 31592051 = 31592284
491 + 31591793 = 31592284
617 + 31591667 = 31592284
683 + 31591601 = 31592284
863 + 31591421 = 31592284
947 + 31591337 = 31592284
953 + 31591331 = 31592284

Showing the first eight; more decompositions exist.
