Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541702, here are decompositions:

43 + 31541659 = 31541702
139 + 31541563 = 31541702
193 + 31541509 = 31541702
421 + 31541281 = 31541702
433 + 31541269 = 31541702
523 + 31541179 = 31541702
541 + 31541161 = 31541702
601 + 31541101 = 31541702

Showing the first eight; more decompositions exist.
