Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624186, here are decompositions:

59 + 31624127 = 31624186
173 + 31624013 = 31624186
197 + 31623989 = 31624186
227 + 31623959 = 31624186
233 + 31623953 = 31624186
239 + 31623947 = 31624186
257 + 31623929 = 31624186
389 + 31623797 = 31624186

Showing the first eight; more decompositions exist.
