Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455754, here are decompositions:

3 + 31455751 = 31455754
41 + 31455713 = 31455754
53 + 31455701 = 31455754
107 + 31455647 = 31455754
131 + 31455623 = 31455754
233 + 31455521 = 31455754
251 + 31455503 = 31455754
383 + 31455371 = 31455754

Showing the first eight; more decompositions exist.
