Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489246, here are decompositions:

3 + 31489243 = 31489246
17 + 31489229 = 31489246
29 + 31489217 = 31489246
53 + 31489193 = 31489246
149 + 31489097 = 31489246
167 + 31489079 = 31489246
419 + 31488827 = 31489246
449 + 31488797 = 31489246

Showing the first eight; more decompositions exist.
