Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544282, here are decompositions:

61 + 31544221 = 31544282
103 + 31544179 = 31544282
151 + 31544131 = 31544282
193 + 31544089 = 31544282
229 + 31544053 = 31544282
241 + 31544041 = 31544282
271 + 31544011 = 31544282
379 + 31543903 = 31544282

Showing the first eight; more decompositions exist.
