Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462884, here are decompositions:

7 + 31462877 = 31462884
53 + 31462831 = 31462884
73 + 31462811 = 31462884
113 + 31462771 = 31462884
127 + 31462757 = 31462884
137 + 31462747 = 31462884
281 + 31462603 = 31462884
293 + 31462591 = 31462884

Showing the first eight; more decompositions exist.
