Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448156, here are decompositions:

7 + 31448149 = 31448156
139 + 31448017 = 31448156
193 + 31447963 = 31448156
199 + 31447957 = 31448156
373 + 31447783 = 31448156
499 + 31447657 = 31448156
823 + 31447333 = 31448156
967 + 31447189 = 31448156

Showing the first eight; more decompositions exist.
