Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541584, here are decompositions:

3 + 31541581 = 31541584
101 + 31541483 = 31541584
167 + 31541417 = 31541584
317 + 31541267 = 31541584
443 + 31541141 = 31541584
467 + 31541117 = 31541584
563 + 31541021 = 31541584
593 + 31540991 = 31541584

Showing the first eight; more decompositions exist.
