Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490152, here are decompositions:

3 + 31490149 = 31490152
53 + 31490099 = 31490152
59 + 31490093 = 31490152
233 + 31489919 = 31490152
251 + 31489901 = 31490152
269 + 31489883 = 31490152
311 + 31489841 = 31490152
401 + 31489751 = 31490152

Showing the first eight; more decompositions exist.
