Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456054, here are decompositions:

41 + 31456013 = 31456054
107 + 31455947 = 31456054
233 + 31455821 = 31456054
251 + 31455803 = 31456054
293 + 31455761 = 31456054
353 + 31455701 = 31456054
431 + 31455623 = 31456054
521 + 31455533 = 31456054

Showing the first eight; more decompositions exist.
