Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447102, here are decompositions:

3 + 31447099 = 31447102
23 + 31447079 = 31447102
59 + 31447043 = 31447102
83 + 31447019 = 31447102
101 + 31447001 = 31447102
149 + 31446953 = 31447102
263 + 31446839 = 31447102
353 + 31446749 = 31447102

Showing the first eight; more decompositions exist.
