Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592212, here are decompositions:

53 + 31592159 = 31592212
83 + 31592129 = 31592212
89 + 31592123 = 31592212
173 + 31592039 = 31592212
233 + 31591979 = 31592212
419 + 31591793 = 31592212
461 + 31591751 = 31592212
479 + 31591733 = 31592212

Showing the first eight; more decompositions exist.
