Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606070, here are decompositions:

3 + 31606067 = 31606070
19 + 31606051 = 31606070
157 + 31605913 = 31606070
193 + 31605877 = 31606070
313 + 31605757 = 31606070
373 + 31605697 = 31606070
487 + 31605583 = 31606070
499 + 31605571 = 31606070

Showing the first eight; more decompositions exist.
