Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592042, here are decompositions:

3 + 31592039 = 31592042
43 + 31591999 = 31592042
199 + 31591843 = 31592042
331 + 31591711 = 31592042
439 + 31591603 = 31592042
661 + 31591381 = 31592042
751 + 31591291 = 31592042
883 + 31591159 = 31592042

Showing the first eight; more decompositions exist.
