Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462700, here are decompositions:

97 + 31462603 = 31462700
109 + 31462591 = 31462700
127 + 31462573 = 31462700
193 + 31462507 = 31462700
229 + 31462471 = 31462700
337 + 31462363 = 31462700
349 + 31462351 = 31462700
433 + 31462267 = 31462700

Showing the first eight; more decompositions exist.
