Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462580, here are decompositions:

3 + 31462577 = 31462580
7 + 31462573 = 31462580
73 + 31462507 = 31462580
109 + 31462471 = 31462580
139 + 31462441 = 31462580
199 + 31462381 = 31462580
223 + 31462357 = 31462580
229 + 31462351 = 31462580

Showing the first eight; more decompositions exist.
