Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592282, here are decompositions:

79 + 31592203 = 31592282
109 + 31592173 = 31592282
229 + 31592053 = 31592282
283 + 31591999 = 31592282
373 + 31591909 = 31592282
409 + 31591873 = 31592282
439 + 31591843 = 31592282
499 + 31591783 = 31592282

Showing the first eight; more decompositions exist.
