Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625702, here are decompositions:

103 + 31625599 = 31625702
139 + 31625563 = 31625702
193 + 31625509 = 31625702
271 + 31625431 = 31625702
421 + 31625281 = 31625702
439 + 31625263 = 31625702
523 + 31625179 = 31625702
571 + 31625131 = 31625702

Showing the first eight; more decompositions exist.
