Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623282, here are decompositions:

59 + 31623223 = 31623282
71 + 31623211 = 31623282
73 + 31623209 = 31623282
83 + 31623199 = 31623282
101 + 31623181 = 31623282
109 + 31623173 = 31623282
113 + 31623169 = 31623282
241 + 31623041 = 31623282

Showing the first eight; more decompositions exist.
