Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455934, here are decompositions:

5 + 31455929 = 31455934
113 + 31455821 = 31455934
131 + 31455803 = 31455934
173 + 31455761 = 31455934
233 + 31455701 = 31455934
311 + 31455623 = 31455934
401 + 31455533 = 31455934
431 + 31455503 = 31455934

Showing the first eight; more decompositions exist.
