Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591592, here are decompositions:

79 + 31591513 = 31591592
139 + 31591453 = 31591592
211 + 31591381 = 31591592
421 + 31591171 = 31591592
433 + 31591159 = 31591592
499 + 31591093 = 31591592
601 + 31590991 = 31591592
661 + 31590931 = 31591592

Showing the first eight; more decompositions exist.
