Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519282, here are decompositions:

29 + 31519253 = 31519282
71 + 31519211 = 31519282
83 + 31519199 = 31519282
89 + 31519193 = 31519282
101 + 31519181 = 31519282
131 + 31519151 = 31519282
173 + 31519109 = 31519282
191 + 31519091 = 31519282

Showing the first eight; more decompositions exist.
